Plain English Summary

3/10 complexity

Requires owners/operators of specified Beechcraft 300-series aircraft to replace both left and right main landing gear actuator clevis assemblies with an improved-design part, following Raytheon Service Bulletin instructions. The replacement must be done within 200 hours time-in-service after 28 January 1999. This measure responds to reported fatigue cracking that could cause gear failure during landing. Operators pay for and schedule the work; the Civil Aviation Safety Authority enforces compliance and relies on the manufacturer’s mandatory service bulletin for the technical steps.

AD/BEECH 300/11 Main Landing Gear Clevis Assembly 1/99

Applicability: Models and serial numbers listed in Raytheon Aircraft Mandatory Service Bulletin (MSB) 2728.

Requirement: Replace the left and right main landing gear actuator clevis assembly with a clevis assembly of improved design in accordance with the Accomplishment Instructions section in Raytheon Aircraft MSB 2728 or MSB 2728 Revision 1.

Note: FAA AD 98-21-35 Amdt 39-10843 refers.

Compliance: Unless already accomplished, within 200 hours time in service after 28 January 1999.

This Airworthiness Directive becomes effective on 28 January 1999.

Background: The FAA received reports of main landing gear failure on two of the affected aircraft. The actions specified by this Directive are intended to prevent failure of the actuator clevis assembly in the main landing gear caused by fatigue cracking of the original design part, which could lead to loss of control of the aircraft during landing operations.
