2011-05-10:
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
* * * * *
Recently, during a walk round check, an operator found an aileron trim tab hinge pin that had migrated sufficiently to cause a rubbing foul on the flap. Other reports indicate that, for the purposes of expediency, it has become common practice during maintenance when replacing a control tab, instead of unbolting the forward part of the piano hinge from the primary control surface, the hinge pins are punched out of the hinges. Investigations have concluded that, after reinserting the pins after maintenance, the ends of the hinges may not have been pinched, which is likely to have been the cause of the detected hinge pin migration.
This condition [non-pinched hinge pin ends], if not detected and corrected, could lead to further incidents of migration of a tab

hinge pin out of the hinge, likely resulting in restricted movement of the tab control and consequent reduced control of the aeroplane.
This AD requires actions that are intended to address the unsafe condition described in the MCAI.

2011-05-08:
This action supersedes emergency airworthiness directive (AD) 2011-05-51 that was sent previously to all known U.S. owners and operators of the products listed above. That AD requires inspecting the fuel ejector in the body of the fuel ejector assembly for proper installation by checking that the circlip is properly seated in its groove. That AD was prompted by three reports of incorrectly assembled low-pressure fuel system ejectors; with one of them resulting in an uncommanded engine in-flight shutdown. This AD requires the same actions and compliance times as the emergency AD, after receipt of the emergency AD, and expands the AD applicability by including helicopters having one or two affected engines and experiencing no starting difficulties. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe conditionas:
In October 2009, Turbomeca issued SB [Service Bulletin] No. 292 73 0826, Version A that instructed operators to check the effectiveness of the bonding of the ejector jet installed on the low-pressure fuel system between the tank and the high-pressure fuel pump.
So far, Turbomeca have been informed of three discrepancies with the reassembly of the ejector following a maintenance procedure performed during accomplishment of Turbomeca SB No. 292 73 0826, Version A.
In all three cases, the discrepancies led to a ``one-off'' abnormal evolution of gas generator (NG) rating during engine starting. In one of these cases, this resulted in an uncommanded in- flight shutdown, during a cruising phase at 8,000 feet.
We are issuing this AD to prevent uncommanded engine in-flight shutdown of one or both engines in a two-engine helicopter and an emergency autorotation landing or accident.

2007-07-06 R1:
We are adopting a new airworthiness directive (AD) to revise AD 2007-07-06, which applies to certain Cessna Aircraft Company (type certificate previously held by Columbia Aircraft Manufacturing) (Cessna) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. AD 2007-07-06 currently requires the following: Adding information to the limitations section of the airplane flight manual (AFM); repetitively inspecting the aileron and the elevator linear bearings and control rods for foreign object debris, scarring, or damage; and taking all necessary corrective actions. Since we issued AD 2007-07-06, Cessna has issued a new service bulletin that contains procedures for installing an access panel to facilitate the required inspections. Consequently, this AD retains the actions currently required in AD 2007-07-06; allows installing access panels; and changes the serial number applicability. We are issuing this AD to prevent jamming in the aileron and elevator control systems, which could result in failure. This failure could lead to loss of control.
DATES: This AD becomes effective on December 5, 2008.
On December 5, 2008, the Director of the Federal Register approved the incorporation by reference of Cessna Mandatory Service Bulletin SB- 07-002D, dated May 29, 2008, and Cessna Mandatory Service Bulletin SB- 07-018, dated May 29, 2008, listed in this AD.
As of April 9, 2007 (72 FR 15822, April 3, 2007), the Director of the Federal Register approved the incorporation by reference of Columbia Mandatory Service Bulletin SB-07-002, dated March 14, 2007, listed in this AD.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI (European Aviation Safety Agency AD 2009- 0192) describes the unsafe condition as:
Performing some quality tests on material, Airbus found that some 300M steel forgings used to manufacture certain landing gear components were below specification limits. Adapted airworthiness limitations were introduced in Airbus A340 Airworthiness Limitations Section (ALS) Part 1 ``Safe Life Airworthiness Limitation Items (SL ALI)'' for different source route codes.
* * * * *
This [EASA] AD introduces more restrictive life limitations for several landing gear components.
The MCAI (EASA AD 2010-0131) describes the unsafe condition as:
* * * * *
The revision 04 of Airbus A330 and A340 ALS Part 1 introduces more restrictive maintenance requirements and/or airworthiness limitations as specified in Airbus A330 and A340 ALS Part 1 revision 04.
The unsafe condition is failure of certain life-limited parts, which could result in reduced structural integrity of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI.

This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
During a normal walkaround check on a F28 Mark 0100 aeroplane, a large crack was discovered in the lower portion of the right (RH) MLG [main landing gear] piston. The affected MLG unit had accumulated 7909 flight cycles (FC) at the time of detection. * * *
This condition, if not detected and corrected, could lead to MLG failure, possibly resulting in loss of control of the aeroplane during the landing roll-out.
We are issuing this AD to require actions to correct the unsafe condition on these products.

This amendment supersedes an existing airworthiness directive (AD), applicable to Hamilton Standard Models 14RF-9, 14RF-19, 14RF-21; and 14SF-5, 14SF-7, 14SF-11, 14SFL11, 14SF-15, 14SF-17, 14SF-19, and 14SF-23; and Hamilton Standard/British Aerospace 6/5500/F propellers, that currently requires that all blades of applicable Hamilton Standard propellers be calibrated for ultrasonic transmissibility before conducting the ultrasonic shear wave inspection. In addition, that AD decreases the repetitive inspection interval for the Hamilton Standard Models 14RF-9, 14SF-5, -7, -11, -15, -17, -19, and -23 propellers from 1,250 flight cycles to 500 flight cycles. That AD also establishes a new ultrasonic shear wave inspection interval of 1,000 flight cycles for the Hamilton Standard Model 14RF-19, and 2,500 flight cycles for the Hamilton Standard Models 14RF-21 and Hamilton Standard/British Aerospace Model 6/5500/F. Also, that AD removes Hamilton Standard Model 14SFL11 propellers from service. This amendment requires a blade repair that constitutes terminating action to the repetitive ultrasonic taper bore inspections. Repetitive ultrasonic taper bore inspections are required until the blade is repaired in accordance with this AD. This amendment is prompted by the development of a taper bore repair process that removes the damaged material and returns the blade to a condition that does not require repetitive ultrasonic taper bore inspections. The actions specified by this AD are intended to prevent separation of a propeller blade due to cracks initiating in the blade taper bore, that can result in aircraft damage, and possible loss of aircraft control.

95-26-16 R1:
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 95-26-16 R1, which was sent previously to all known U.S. owners and operators of certain Mooney Aircraft Corporation (Mooney) Model M20J airplanes. This AD requires repetitively inspecting the alternate air door assembly to ensure a cotter pin exists and is secure, and replacing the cotter pin if it does not exist or is not secure. It also provides the option of incorporating an alternate air door plate assembly of improved design as terminating action for the repetitive inspections. Priority letter AD 95-26-16 R1 was prompted by a fatal accident involving one of the affected airplanes where the alternate air door became lodged in the air intake of the fuel injector causing engine failure. The actions specified by this AD are intended to prevent the alternate air door from separating from the airplane and restricting air flow to the engine.

To prevent possible cylinder head to barrel separation, engine failure and/or engine compartment fire, accomplish the following:
(a) For the above cylinder assembly part numbers installed on engines including those serial numbered engines listed above:
(1) Determine the part number for each cylinder assembly (part number is stamped on flange of cylinder barrel) and the date of manufacture (month and year of manufacture are stamped underneath rocker cover on the face of the rocker shaft boss).
(i) If the cylinder assembly part number and date of manufacture are as listed above, proceed with paragraphs (2), (3), (4), (5), and (6).
(ii) If the cylinder assembly part number and date of manufacture are not as listed above, proceed to paragraph (6). No further inspections are required by this AD.
(2) Visually inspect all cylinders for oil stains or leakage between the first and second barrel fins from the bottom of the head casting. The area of concern on direct drive engines is at the 12 o'clock position on the 1-3-5 cylinder side and the 6 o'clock position on the 2-4-6 side. On the GTSIO series engine, the area of concern is at the 6 o'clock position on the 1-3-5 cylinder side and the 12 o'clock position on the 2-4-6 cylinder side.
(3) Pressure check all cylinder assemblies using a differential compression tester. The piston should be as close to BDC (Bottom Dead Center) as possible to insure the piston and rings are below the inspection area specified in paragraph (2) but still keeping both valves closed and maintaining pressure in the cylinder. With 80 PSIG (pounds per square inch gauge) air pressure in the cylinder, check the area specified in paragraph (2) with a soap/water solution and inspect for any leakage.
(4) If any leakage is noted from the above inspection and/or pressure check, the cylinder assembly must be changed before further flight.
NOTE: TCM Service Bulletin M86-7, Revision 5, dated November 15, 1986, advises that extreme caution be used in the area of the propeller while performing this inspection.
(5) This visual inspection and pressure check must be repeated at intervals not to exceed 50 flight hours until the last inspection and pressure check required by this ADhas been accomplished. The last inspection and pressure check required by this AD must occur between 440 hours and 490 hours of cylinder operation.
(6) The repetitive inspections and pressure checks described above may be discontinued when one of the following has been accomplished:
(i) Suspect cylinder assemblies have been replaced with assemblies having a date of manufacture prior to January 1985.
(ii) Approved replacement cylinder assemblies having different part numbers are installed provided these replacement cylinder assemblies are not reworked from the assembly part numbers listed above.
(iii) New design pistons (as shown below) are installed, and the affected cylinder assembly has the letter "P" stamped or vibro-etched on the face of the rocker shaft boss adjacent to the manufacture date, i.e. 5-85P.

(7) Make appropriate Engine Logbook entry.
(b) For the above cylinder assembly part numbers not installed on engines, confirm a manufacture date stamp of 1-85 (January 1985) or subsequent (month and year of manufacture are stamped underneath rocker cover on the face of the rocker shaft boss), then notify TCM for disposition and replacement.
(c) Comply with the provisions of this AD for the above cylinder assembly part numbers which are reworked and/or reidentified with a different part number.
NOTE: TCM Service Bulletin No.'s M86-7, Revision 5, dated November 15, 1986, and M87-19, dated September 17, 1987, address this subject.
(d) Aircraft may be ferried in accordance with the provisions of FAR 21.197 and 21.199 to a base where the AD can be accomplished.
(e) Upon request, an equivalent means of compliance with the requirements of this AD may be approved by the Manager, Atlanta Aircraft Certification Office, 1669 Phoenix Parkway, Suite 210C, Atlanta, Georgia 30349.
(f) Upon submission of substantiatingdata by an owner or operator through an FAA maintenance inspector, the Manager, Atlanta Aircraft Certification Office, 1669 Phoenix Parkway, Suite 210C, Atlanta, Georgia 30349, may adjust the compliance time specified in this AD.
AD 86-13-04, Amendment 39-5345, became effective July 11, 1986.
Priority Letter AD 86-13-04 R1, issued September 5, 1986, became effective immediately upon receipt.
Amendment 39-5555 (AD 86-13-04 R2) became effective February 19, 1987, as to all persons except those persons to whom it was made immediately effective by Priority Letter AD No. 86-13-04 R2, issued December 24, 1986.
This amendment, 39-5850, (AD 86-13-04 R3) becomes effective February 24, 1988, as to all persons except those persons to whom it was made immediately effective by priority letter AD 86-13-04 R3 issued November 10, 1987, which contained this amendment.

2010-07-04:
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
It has been determined that due to an intermittent communication between AMS [Air Management System] controller cards and both Secondary Power Distribution Assemblies (SPDAs) the message "RECIRC SMK DET FAIL'' is displayed in the Engine Indication and Crew Alerting System (EICAS). This communication failure could result in loss of automatic activation of engine inlet ice protection system when in ice condition. In this situation the caution messages "A-I Eng 1 Fail'' and "A-I Eng 2 Fail'' will be displayed and if the flight crews do not follow the associated procedures ice may accrete in the engines inlet and cause a dual engine shut down.
* * * * *
This AD requires actions that are intended to address the unsafe condition described in the MCAI.

Replace the actuator with a serviceable part if staining or pitting is found, except for staining between lands in the machined clearance areas if no scaling rust or corrosive debris is present. A follow-on spool inspection is not required unless the repetitive fluid contamination level test cited in paragraph (b) shows an increase in chlorine contamination levels. Prior to returning the actuator to service, replace shutoff valve lap assembly P/N 1303-084, Rev. C, with shutoff valve lap assembly P/N 1303-084, Rev. D.
(d) Within the next 25 hours time in service from the effective date of this AD, unless already accomplished within the last 575 hours time in service, and thereafter at intervals not to exceed 600 hours time in service, replace the six NAS 1351-3H1OP cap screws that attach the gland retainers, P/N 1303-044, to the actuator manifold assembly, P/N 1303-010, on all four lower boost dual actuating cylinders, P/N's 234HS560-1 and -2, with zero time screws. Torque the new screws to a value of 30- to 35-inch-pounds (wet).
(e) Within the next 25 hours time in service from the effective date of this AD, unless already accomplished within the last 25 hours time in service, and thereafter at intervals not to exceed 25 hours time in service, conduct the inspections, jam indicator button checks, leakage checks, and safety wire replacement contained in paragraphs 3A, 3B, 3C, 3D, and 3E of Boeing Vertol telex No. 8-1420-3-5455 dated May 25, 1984, or an equivalent approved by the Manager, New York Aircraft Certification Office, 181 South Franklin Avenue, Valley Stream, New York 11581.
