Compliance required as indicated unless previously accomplished. A. Unless the inspection requirements of paragraph B., below, have been accomplished within the previous 2,000 flight hours or 1,000 landings, whichever came first, revise the Lockheed L-1011 FAA approved airplane flight manual (AFM) LR-25925 within 5 calendar days after receipt of this airworthiness directive (AD), to add the following and provide to flight crews: SECTION 1 - LIMITATIONS Fuel System 1. In addition to normal fuel reserve requirements, flight planning must be predicated on the following: A) A fuel fitting failure, occurs to engine No. 1 or 3 at any time during the flight; B) 10,000 pounds of fuel will be lost overboard while the flight crew recognizes and reacts to a fuel line failure; C) At the time of fuel line failure, the respective No. 1 or 3 engine is considered to become inoperative; and D) At the time of failure, the flight can be continued to a suitable airport. 2. Cockpit fuel totalizer and fuel quantity indicating systems for tanks 1 and 3 must be operational prior to takeoff. Aircraft equipped with tanks 1A and 3A, when fueled, must have the respective cockpit fuel quantity indicating systems operational prior to takeoff. 3. The fuel quantity must be closely monitored and compared with total fuel used at 5 minute maximum intervals during flight. SECTION 2 - EMERGENCIES Rapidly Decreasing Fuel Quantity Indication Reference. If fuel quantity indication decreases at an abnormally high rate, assume a leak in the fuel line to engine No. 1 or 3 and proceed as follows: 1. All fuel crossfeed valves close 2. All fuel quantity indicators monitor 3A. If fuel quantity indication in tanks 1 and 3 decrease at a normal rate, resume normal operation. 3B. If fuel quantity indication continues to decrease abnormally in tanks 1 or 3: 1.) Fuel tank pumps (in affected tank) off 2.) Affected engine shut down 3.) Affected tank valve close 4.) Fuel quantity indicators (Tank 1 and 3) monitor 5.) Aircraft range check 6.) With tank valve closed, remaining fuel in affected tank is available to the other engines by use of crossfeed procedures. B. Within 1,000 hours time in service, or ninety (90) days after the effective date of this amendment, whichever occurs first, inspect and replace, if necessary, P/N 741266-101 fuel line fittings as specified in Paragraph 2, Accomplishment Instructions of Lockheed L-1011 Service Bulletin 093-28-072, dated July 23, 1984; or later revisions approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region. Repetitive inspections of P/N 741266-101 fuel line fittings are required at 1000 landing intervals using visual inspections, or 1500 landing intervals using eddy current inspections, until P/N 741266-105 fuel line fittings are installed. NOTE: Installation of P/N 741266-105 fuel line fittings is terminating action for this AD. C. A copy of this AD inserted in the FAA approved AFM may be considered as an acceptable means of compliance with required AFM revisions. D. Alternate means of compliance which provide an equivalent level of safety may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region. E.

2010-23-01: We are adopting a new airworthiness directive (AD) for the products listed above. 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 condition as: Some cases of corrosion were detected in the interface between the elevator hinges fittings (metallic) and the horizontal stabilizer (carbon fibre); investigation identified the cause in galvanic corrosion between dissimilar materials. If left uncorrected, this situation could lead to a structural failure of the elevator, which could result in possible loss of control of the aeroplane. We are issuing this AD to require actions to correct the unsafe condition on these products.
87-04-19: 87-04-19 EON CORPORATION: Amendment 39-5552. Applies to EON Corporation TSO C22 safety belt assemblies incorporating E6000 buckle assemblies. \n\n\tCompliance is required within 30 days after the effective date of this AD, unless previously accomplished. \n\n\tTo prevent inadvertent opening of safety belt assemblies, accomplish the following: \n\n\t\tA.\tInspect all EON Corporation TSO C22 safety belt assemblies to determine if they use E6000 buckle assemblies. If a safety belt assembly with E6000 buckles is installed, remove and replace it with another FAA-approved safety belt assembly. The removed belts, if not destroyed, must have the TSO approval markings either permanently obliterated or removed. \n\n\tNOTE: This type of buckle assembly has a front cover plate which is pivoted at one end and is pulled at the other end through an arc to release the latch from the buckle. The E6000 buckle assemblies can be identified by the type of catch they use. Figure 1 (following) shows theconfiguration of the catch and how it is located within the buckle assembly. \n\n\t\tB.\tAlternate means of compliance which provide an acceptable level of safety may be used when approved by the Manager, Western Aircraft Certification Office, FAA, Northwest Mountain Region. \n\n\tThis amendment becomes effective March 18, 1987.

For Model SD3-30 series airplanes, modify the ECE electrical contactors on panels 1C and 2C in accordance with the Accomplishment Instructions of Shorts Service Bulletin SD330-24-21, Revision 1, dated October 1986. B. For Model SD3-60 series airplanes, modify the ECE electrical contactors on panels 1C and 2C in accordance with the Accomplishment Instructions of Shorts Service Bulletin SD360-24-06, dated August 1986. C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety and which has the concurrence of an FAA Principal Maintenance Inspector, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Northwest Mountain Region. D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of the modifications required by this AD. All persons affected by this directive who have not already received the appropriate service document from the manufacturer may obtain copies upon request to Short Brothers, 2011 Crystal Drive, Suite 713, Arlington, Virginia 22202-3702. This document may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.

2010-20-23: The FAA is superseding an existing airworthiness directive (AD) for certain serial numbers (S/Ns) of Bombardier-Rotax GmbH type 912 F and 914 F series reciprocating engines. That AD currently requires initial and repetitive visual inspections of the engine crankcase for cracks. This AD requires those same inspections, adds the 912 S series to the affected population, adds a test procedure to determine the engine suitability for a special flight permit, and changes applicability from engine S/N to crankcase S/N. This AD results from an increase in the affected crankcase population. We are issuing this AD to prevent oil loss caused by cracks in the engine crankcase, which could lead to in-flight failure of the engine and forced landing.
2010-22-06: 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: An A330 experienced an uncommanded engine 1 in flight spool down, which occurred while applying fuel gravity feed procedure, in response to low pressure indications from all fuel boost pumps, in both left and right wings. The investigations revealed that the wing tank pressure switches P/N (part number) HTE69000-1 had frozen due to water accumulated in their external part, causing spurious low pressure indications. As per procedure, the main pumps are then switched off, increasing the level of unavailable fuel. This, in combination with very low fuel quantities or another independent trapped fuel failure scenarios, can lead to fuel starvation on the affected engine(s). * * * * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
