To prevent fracture of the combustion chamber which could result in an uncontained engine failure, accomplish the following: NOTES: 1) For the initial inspection, time since inspection (TSI) is defined as hours or cycles since installation by Aerothrust. Thereafter, for the repetitive inspections, TSI is defined as hours or cycles since the last inspection. 2) For the initial inspection, the cumulative crack length at the 2-3 seam weld is that present at the time of installation by Aerothrust as determined by individual chamber x-ray film records on file at Aerothrust. 3) Investigation is continuing and pending the results, additional engine serial numbers may be added to this AD. (a) Remove from service within the next 100 hours or 100cycles time in service from the effective date of this AD, whichever occurs first, chambers with greater than 8 inches but less than or equal to 12 inches cumulative crack length at installation by Aerothrust. (b) Remove from service, prior to further flight, chambers with greater than 12 inches cumulative crack length at installation by Aerothrust. (c) Inspect combustion chamber 2-3 seam welds in accordance with PW Service Bulletin Number 5639, dated November 15, 1985, or FAA approved equivalent, per the following schedule: (1) Inspect chambers with 3 inches or less cumulative crack length as follows: (i) Prior to accumulating 2,000 hours or 1,500 cycles TSI, whichever occurs first; or (ii) For chambers with greater than 1,900 hours or 1,400 cycles TSI on the effective date of this AD, inspect within the next 100 hours or 100 cycles time in service, whichever occurs first. (2) Inspect chambers with greater than 3 inches but less than or equal to 6 inches cumulative crack length as follows: (i) Prior to accumulating 1,500 hours or 1,000 cycles TSI, whichever occurs first; or (ii) For chambers with greater than 1,400 hours or 900 cycles TSI on the effective date of this AD, inspect within the next 100 hours or 100 cycles time in service, whichever occurs first. (3) Inspect chambers with greater than 6 inches but less than or equal to 8 inches cumulative crack length as follows: (i) Prior to accumulating 250 hours or 200 cycles TSI, whichever occurs first; or (ii) For chambers with greater than 150 hours or 100 cycles TSI on the effective date of this AD, inspect within the next 100 hours or 100 cycles time in service, whichever occurs first. (4) Chambers for which the cumulative crack length at installation by Aerothrust cannot be confirmed must be inspected within the next 100 hours or 100 cycles time in service, whichever occurs first. (d) Reinspect chambers, thereafter, in accordancewith the appropriate inspection interval of paragraphs (c)(1) through (c(3), as determined by the crack length at last inspection or at installation by Aerothrust, whichever crack length is greater. Remove from service, prior to further flight, any chambers with greater than 8 inches cumulative crack length at reinspection. 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. Upon request, an equivalent means of compliance with the requirements of this AD may be approved by the Manager, Engine Certification Office, New England Region.

2024-25-04: The FAA is superseding Airworthiness Directive (AD) 2023-23- 10, which applied to all Embraer S.A. Model ERJ 190-300 airplanes. AD 2023-23-10 required repetitive inspections of the press-fitted bushings of the wing ailerons for migration and broken sealant, measurements of the distance between the aileron surfaces and hinge fittings, functional checks of the backlash of the wing aileron control system, and all applicable related investigative and corrective actions. Since the FAA issued AD 2023-23-10, it was determined that certain requirements needed to be clarified. This AD continues to require all actions of ANAC AD 2023-06-01 with revised compliance requirements, as specified in an Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

2021-09-11: The FAA is adopting a new airworthiness directive (AD) for all Saab AB, Support and Services Model SAAB 2000 airplanes. This AD was prompted by a report indicating that the left-hand main landing gear (MLG) collapsed after touchdown, causing severe damage to the airplane. This AD requires modifying the MLG hydraulic transfer valve, 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.

Airworthiness Directive 91-15-15, published in the Federal Register on July 26, 1991, was not distributed to the public by FAA due to a clerical error in the AD.

2003-16-09: This amendment adopts a new airworthiness directive (AD) that is applicable to certain Learjet Model 45 airplanes. This action incorporates a reduced life-limit replacement interval for certain shear pins in the trunnion assemblies of the main landing gears (MLG) into the airworthiness limitations section of the Instructions for Continued Airworthiness, and requires replacement of those certain shear pins with new, improved shear pins. This action is necessary to prevent failure of the shear pins in the trunnion assemblies of the MLGs, which could result in the collapse of a MLG, and consequent reduced controllability of the airplane during takeoff or landing. This action is intended to address the identified unsafe condition.
2002-24-08: This amendment supersedes Airworthiness Directive (AD) 2002- 05-05, which currently applies to certain Cirrus Design Corporation (Cirrus) Models SR20 and SR22 airplanes. AD 2002-05-05 currently requires you to incorporate temporary operating limitations into the Limitation Section of the airplane flight manual (AFM) for certain affected airplanes and install a cable clamp external to the cone adapter on the Cirrus Airplane Parachute System (CAPS) activation cable for all affected airplanes. AD 2002-05-05 resulted from a report from the manufacturer that certain CAPS may not activate in an emergency situation. This AD is the result of the manufacturer redesigning the CAPS activation system. This AD requires you to modify the CAPS activation system. The actions specified by this AD are intended to prevent failure of the CAPS activation system in an emergency situation. Failure of this system could result in occupant injury and/ or loss of life and loss of aircraft.
2002-24-07: This amendment adopts a new airworthiness directive (AD) that applies to certain Aerostar Aircraft Corporation (Aerostar) Models PA- 60-601 (Aerostar 601), PA-60-601P (Aerostar 601P), PA-60-602P (Aerostar 602P), and PA-60-700P (Aerostar 700P). This AD requires you to replace Roto-Master and Rajay scavenge pumps with improved design Aerostar scavenge pumps. This AD is the result of failures of the existing Roto- Master and Rajay scavenge pumps found during regular maintenance inspections. The actions specified by this AD are intended to prevent in-flight failure of the oil scavenge pumps, which could result in loss of engine oil and possible loss of engine power.
