Plain English Summary

3/10 complexity

This AD requires operators of Boeing 767s (line positions 001–402) to carry out inspections and any corrective actions per Boeing Service Bulletin 767‑27A0094 Revision 4, targeting LE slat shutoff/control and rigging and the TE flap by‑pass valve motor. CASA makes compliance mandatory (operators pay for and arrange work); the action responds to uncommanded slat extension and TE by‑pass failures and aligns with FAA guidance. The AD enforces the SB as the compliance document, creating a procedural and cost burden for affected operators.

Amdt 1

High Lift System 4/94

Applicability: All model 767 series aeroplanes with line position 001 through 402 inclusive. Requirement: Action in accordance with Boeing SB 767-27A0094 Revision 4.

Note: FAA AD 93-19-05 amdt 39-8703 supersedes FAA AD 89-26-04 amdt 39-6423.

Compliance: As specified in the requirement document.

Background: A report of an uncommanded slat extension during cruise, and several instances of an inoperative trailing edge flap by-pass motor have prompted the issue of this Airworthiness Directive; which requires regular inspections of the LE slat shutoff valve, the LE slat long term shutoff control, the inboard and outboard LE slat drive mechanical rigging and the TE flap by-pass valve motor.

This revision raised in sequence to specify the aircraft S/N range, to amend the FAA AD reference and to update the requirement document reference.
