COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Piper PA-42 (Cheyenne III) Series Aeroplanes
AD/PA-42/4
Amdt 1
Main Landing Gear Pivot Shaft Assembly Bolts 8/85
Applicability: All model PA-42 with S/Nos referenced in Piper Service Bulletin NO. 768A. Requirement: Action in accordance with Piper SB. No. 768A.
Compliance: Unless previously accomplished, within 100 hours time in service after 31 August 1985 or at the next scheduled inspection for Maintenance Release issue after 31 August 1985, whichever is the later.
Background: The possibility exists that the bolts securing the main landing gear pivot shaft assembly to the main spar may be of insufficient length, thus preventing full thread engagement into the nut plates. Revision “A” to Piper SB No. 768 extends serial number applicability.
