Airworthiness Directive 2005-04-14
recurringAirworthiness Directives; Boeing Model 757-200, 757-200CB, and 757-200PF Series Airplanes Equipped With Rolls Royce Model RB211 Engines
What this AD requires
The FAA is revising an existing airworthiness directive (AD), which applies to certain Boeing Model 757-200, 757-200CB, and 757-200PF series airplanes. That AD currently requires repetitive inspections to detect horizontal or vertical movement of the shims at the joint of the mid-bulkhead and the upper link fittings; repetitive inspections for cracking of the mid-bulkhead; and corrective action if necessary. That AD also provides optional terminating action for the repetitive inspections. This AD continues to require the existing requirements and optional actions and clarifies certain terminating actions. This AD results from comments received in response to an existing AD, requesting clarification. We are issuing this AD to detect and correct migration of shims at the joint of the mid-bulkhead and the upper link fittings and cracking of the mid-bulkhead, which could result in cracking of the strut and consequent loss of the strut and engine.
Which aircraft AD 2005-04-14 applies to
Applies to airplanes certificated in any category, equipped with Rolls-Royce RB211 engines, as identified in Boeing Service Bulletin 757-54A0039, Revision 3, dated January 13, 2005; concerns mid-bulkhead/strut cracking.
Whether AD 2005-04-14 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
