2002-23-11: This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) 200, 300, and 1900 series, and Models F90 and A100-1 airplanes. This AD requires you to check the airplane logbook to determine if the elevator(s) has/have been removed from the airplane. If the elevator(s) has/have been removed, this AD also requires you to inspect the elevator balance weight attachment screws for correct length, and, if necessary, install new bolts that are of improved design and rebalance the elevator, depending on the results of the inspection. This AD is the result of the elevator balance weight attachment screws and balance weights being improperly installed when balancing the elevator after it had been removed for repair or repainting. The actions specified by this AD are intended to prevent the balance weight attachment screws from becoming loose. Loose screws could come into contact and interfere with the horizontal stabilizer. This interference could restrict elevator movement and result in loss of elevator pitch control.
2002-23-06: This amendment supersedes an emergency airworthiness directive (AD) that was sent previously to all known U.S. owners and operators of Textron Lycoming (T/L) AEIO-540, IO-540, LTIO-540, O-540, and TIO-540 series reciprocating engines. That action requires replacing certain zinc-plated crankshaft gear retaining bolts. This action still requires replacing certain zinc-plated crankshaft gear retaining bolts, but expands the population of affected engines. This amendment is prompted by two recent failures of zinc-plated crankshaft gear retaining bolts, and a reassessment of the extent to which the suspect bolts may still be present in the field. The actions specified by this AD are intended to prevent loss of all engine power and possible forced landing.
99-21-17: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A321 series airplanes. This action requires reinforcement of the fuselage structure between frames 62 and 64. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent the loss of structural integrity of the rear part of the fuselage structure in the event of an undetected tail scrape during landing or takeoff.
2024-05-07: The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AW189 helicopters. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the airworthiness limitations section (ALS) of the existing helicopter maintenance manual or instructions for continued airworthiness (ICA) for your helicopter and the existing approved maintenance or inspection program for your helicopter, as applicable, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
2011-05-12: We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive detailed inspections for disbonding and tearing and measurements for wear of the internal diameter (ID) of the Karon-lined bushings of the bulkhead support jackscrew fitting and of the jackscrew fitting of the horizontal stabilizer; and reinstallation of the horizontal stabilizer trim actuator (HSTA) after inspection and measurement; and if necessary, replacement of the bushings with new bushings and all applicable related investigative and corrective actions. This AD was prompted by a report indicating that a Karon-lined bushing with the liner broken into five pieces was found during a scheduled inspection of the HSTA components; the broken liner had worn and disbonded from the bushing. We are issuing this AD to detect and correct discrepancies of the HSTA attachment locations, which could result in reduced structural integrity of the horizontal stabilizer and consequent loss of controllability of the airplane.
2002-23-01: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Gulfstream Aerospace LP Model Galaxy and Gulfstream 200 airplanes. This action requires a one-time inspection for evidence of damage to the forward engine cross spar assembly; and repair if necessary. This action is necessary to detect and correct damage to the forward engine cross spar assembly, which could result in reduced structural integrity of the forward engine cross spar assembly. This action is intended to address the identified unsafe condition.
2024-06-51: The FAA is superseding airworthiness directive (AD) 2024-05- 51, which applied to certain General Electric Company (GE) Model CT7- 2E1, CT7-2F1, CT7-8A, CT7-8E, and CT7-8F5 engines, and various restricted category helicopters with GE Model T700-GE-700, -701A, - 701C, -701D/CC, -701D, -401, -401C, CT7-2D, or CT7-2D1 engines installed. AD 2024-05-51 required a phase array ultrasonic inspection of the torque reference tube magnetic insert braze joint of the power turbine (PT) drive shaft assembly for inadequate braze coverage, and repair or replacement of the PT drive shaft assembly if necessary. This AD was prompted by at least four reports of failures of the torque reference tube magnetic insert braze joint of the PT drive shaft assembly within the last several months. This AD retains the requirements of AD 2024-05-51 and expands the applicability to include a PT drive shaft assembly part number that was inadvertently omitted. The FAA previously sent an emergency AD to all known U.S. owners and operators of these engines and helicopters and is now issuing this AD to address the unsafe condition on these products.
98-12-28: This amendment adopts a new airworthiness directive (AD), applicable to all CASA Model C-212 series airplanes, that requires repetitive inspections for cracking in the false spar of the wing, and repair, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to detect and correct cracking in the false spar, which could result in reduced structural integrity of the wing.
81-06-51 R1: 81-06-51 R1 BOEING: Amendment 39-4110 as amended by Amendment 39-4445. Applies to Boeing Model 707/720 series airplanes, certificated in all categories, prior to line number 885. To assure continued structural integrity of the outboard wing, accomplish the following within the next 75 hours time-in-service unless accomplished since January 1, 1980: \n\n\t1.\tPerform a one-time visual inspection and repeat visual inspections at intervals not exceeding one year, in accordance with Boeing Service Bulletin A3308, Revision 2, dated July 10, 1981, or later revision approved by the Manager, Seattle Area Aircraft Certification Office, FAA Northwest Mountain Region. The first repetitive inspection shall be accomplished within a year of the last inspection (AD 81-06-51) or within 90 days after the effective date of this amendment, whichever occurs later. \n\n\t2.\tAfter inspection, spray the area with BMS 3-23 organic corrosion inhibitor or equivalent.\n \n\t3.\tParts found cracked must be repaired in accordance with Boeing Service Bulletin A3308 or replaced prior to further flight except that airplanes may be flown to a maintenance base for repairs or replacement in accordance with FAR 21.197 and 21.199 with prior approval of the Chief, Seattle Area Aircraft Certification Office, FAA Northwest Region.\n\n \t4.\tEquivalent inspections and repairs may be used when approved by the Chief, Seattle Area Aircraft Certification Office, FAA Northwest Region.\n \n\tThe manufacturers specifications and procedures identified and described in this amendment are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1). \n\n\tAll persons affected by this directive who have not already received the service document from the manufacturer may obtain copies upon request to The Boeing Company, P.O. Box 3707, Seattle, Washington 98124. These documents also may be examined at FAA Northwest Mountain Region, 9010 East Marginal Way South, Seattle, Washington. \n\n\tAmendment 39-4110 became effective May 18, 1981, and was effective earlier to those recipients of telegraphic AD T81-06-51, dated March 6, 1981. \n\n\tThis Amendment 39-4445 becomes effective September 30, 1982.
