Plain English Summary

4/10 complexity

This AD requires operators of certain Boeing 767s to carry out the inspections, modifications and repairs specified in FAA AD 91-12-16 and Boeing Alert Service Bulletin 767-29A0038, to be completed within 3,600 flight hours or 24 months. CASA mandates compliance; operators (or their maintenance providers) arrange and pay for the work. The measures address FAA-identified risk that structural damage could impair all three hydraulic systems and lead to loss of controllability.

Boeing 767 Series Aeroplanes

AD/B767/58 Left Hydraulic System 9/91

Applicability: Boeing 767 series Aeroplanes as listed in Boeing Alert Service Bulletin 767- 29A0038, dated 3 August 1989.

Requirement: Action in accordance with the Technical Requirements of FAA AD 91-12-16.

Note: FAA AD 91-12-16 refers to Boeing Alert Service Bulletin 767-29A0038, Amendment 39-7028.

Compliance: Required within 3600 hours time-in-service or 24 months from the issue date of this AD, whichever occurs later.

Background: FAA AD action was prompted by review and analysis of the B767 flight control system functional redundancy as it relates to the ability of the aeroplane to continue safe flight and landing after structural failure. This condition, if not corrected, could result in loss of controllability of the aeroplane if, following a single event of structural failure, damage occurs to all three hydraulic systems.
