2018-11-12: We are adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL- 600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a report that Belleville washers installed on the shimmy damper of the main landing gear (MLG) may fail due to fatigue. This AD requires revising the maintenance or inspection program, as applicable, to incorporate a repetitive task specified in the maintenance review board (MRB) report. We are issuing this AD to address the unsafe condition on these products.
2000-05-04: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes, that requires repetitive inspections to detect cracking of the fuselage skin in the area of the VHF2 antenna, and repair, if necessary. This amendment also provides for optional terminating action for the repetitive inspections. 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 such cracking, which could result in cabin depressurization of the airplane.
58-04-02: 58-04-02 HARTZELL: Applies to All HC-93Z20-2C and -2B Propellers. The -2C Propellers Are Installed on All Beech E50 and F50 Aircraft, and -2B Propellers Are Installed on Some Cessna T-50 With Lycoming R-680 Engines and on Mansdorf Conversion of Grumman G- 44 With Lycoming R-680 Engines (STC SA4-2). Compliance required prior to next flight for propellers with hub Serial Numbers 100A through 361A and above. The recent failure of an A-1307 split ring, which the records show had less than 180 hours' operating time, permitted the propeller blade to leave the hub. In order to minimize the possibility of the occurrence of this type of serious failure, the present split ring must be replaced with a strengthened split ring. Accordingly, replace A-1307 split ring with A-1331 split ring. This also requires replacing A-1303 bearing with A-1303A bearing. Modified propellers should be stamped HC-93Z20-2B1 or -2C1. New propellers so stamped will incorporate modified split rings and bearings. (Hartzell Service Bulletin No. 55 covers this same subject.)
2000-04-22: This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce plc (RR) RB211-524G2-T-19; RB211-524G3-T-19; RB211-524H2-T-19; RB211 Trent 768-60; and RB211 Trent 772-60 turbofan engines. This AD requires the replacement of the joint bolt assemblies that secure the high-pressure compressor (HPC) to the high-pressure turbine (HPT) of the RB211-524 series and Trent 768 and 772 series turbofan engines. This amendment is prompted by six incidents of bolt failure, one of which resulted in a damaged stage 6 HPC disk following an impact with a separated bolt head. The actions specified in this AD are intended to prevent failure of the HPC-to-HPT joint bolt assemblies, which could result in a cracked stage 6 HPC disk, possible uncontained engine failure, and damage to the airplane.
2020-22-09: The FAA is superseding Airworthiness Directive (AD) 2001-16- 13, which applied to certain Airbus SAS Model A330 series airplanes. AD 2001-16-13 required a roto-test inspection of fastener holes of certain fuselage joints for cracks, reinforcement of the fuselage between certain frames, and, if necessary, a high frequency eddy current (HFEC) inspection and repair. As published, the applicability of AD 2001-16-13 inadvertently identified the model designations as serial numbers. This document corrects that error. This new AD requires a roto-test inspection of fastener holes of certain fuselage joints for cracks, reinforcement of the fuselage, and, if necessary, an HFEC inspection and repair. The FAA is issuing this AD to address the unsafe condition on these products.
2020-22-14: The FAA is superseding Airworthiness Directive (AD) 2018-07-16 for all Austro Engine GmbH model E4 and E4P diesel piston engines. AD 2018-07-16 required initial and repetitive replacement of the waste gate controller and the control rod circlip. This AD retains the requirements of AD 2018-07-16 and requires engine modification by installing a waste gate control-rod fail-safe bridge and new spring- loaded circlip that terminates the initial and repetitive replacement requirements of AD 2018-07-16. This AD was prompted by the development of a modification of the waste gate control rod by adding a fail-safe bridge and spring-loaded circlip. The FAA is issuing this AD to address the unsafe condition on these products.
2018-11-08: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200 and -300 series airplanes.
