Airworthiness Directive · Amendment 39-9018 · Saab AB, Saab Aerosystems Airplanes
Saab AB, Saab Aerosystems Airplanes
This AD applies to Saab AB, Saab Aerosystems SAAB 340B, 340A (SAAB SF340A).
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SF340A and SAAB 340B series airplanes. This amendment requires inspections to detect discrepancies of certain main landing gear (MLG) retract actuator bracket retaining bolts; replacement of discrepant parts; installation of washers, if necessary; and eventual replacement of certain MLG retract actuator bracket retaining bolts and certain nose landing gear (NLG) trunnion pin cross bolts. This amendment is prompted by reports of extension and retraction problems on the MLG, due to loose retract actuator brackets on the MLG shock struts. The actions specified by this AD are intended to prevent a loose retract actuator bracket from interfering with the MLG shock strut trunnion support, which could result in the inability of the MLG to extend or retract.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
