Applicability: All Model 737-100, -200, -300, -400, and -500 series aircraft.

Requirement: Action in accordance with the technical requirements of FAA AD 99-19-27 Amdt 39- 11314.

For the purposes of this Directive, in FAA AD 99-19-27, substitute CASA-approved maintenance program for FAA-approved maintenance program.

Background: The FAA received reports of incidents of multiple tie bolt failures on certain BFGoodrich wheel assemblies. Failure of multiple tie bolts of main landing gear wheel assemblies could result in failure of the wheel rim, rapid release of tyre pressure, and probable consequent damage to the aircraft and injury to passengers and flight crew.

Amendment 1 is issued to correct a typographical error in the Requirement section of this Directive.

The original issue of this Airworthiness Directive became effective on 30 December 1999.
