Plain English Summary

3/10 complexity

This airworthiness directive requires operators of certain Boeing 767 aeroplanes to install an upgraded Engine Indicating and Crew Alerting System (EICAS) computer, following specified Boeing service bulletins. It applies to 767s identified by those bulletins with either General Electric or Rolls‑Royce RB211 engines and sets firm compliance dates.

The stated purpose is to ensure flight crews receive warnings of an impending fuel‑filter bypass (a contamination condition that can increase engine power‑loss risk). Operators must schedule and pay for the retrofit and follow the service instructions.

Amdt 1

Engine Indicating and Crew Alerting System 2/2002

Applicability: Model 767 series aeroplanes identified in Boeing Service Bulletins (SB) 767-31-0098 dated 27 August 1998, 767-31-0091 Revision 1 dated 4 February 1999 or 767-31-

0099 Revision 3 dated 8 February 2001.

Requirement: 1. For aeroplanes with General Electric engines - Install an upgraded engine indicating and crew alerting system (EICAS) computer in accordance with either SB 767-31-0098 or 767-31-0091 Revision 1, as applicable.

For aeroplanes with Rolls Royce engines - Unless previously accomplished, install an upgraded EICAS computer in accordance with SB 767-31-0099 Revision 3 dated 8 February 2001.

Note: FAA AD 96-07-09 Amdt 39-9558 refers.

Compliance: For Requirement 1 - Remains unchanged, No later than 1 June 2001.

For Requirement 2 - No later than 21 March 2002.

This Amendment becomes effective on 21 February 2002.

Background: The Federal Aviation Administration issued an airworthiness directive following a finding that EICAS computers currently installed on certain Boeing 767 aeroplanes do not provide an appropriate indication to the flight crew of an impending fuel filter bypass condition. Replacement of the EICAS computer ensures that the flight crew is aware of conditions involving a severely contaminated fuel system and the associated increased potential for engine power loss.

The original issue of this Directive addressed 767 aeroplanes with engines manufactured by General Electric. This amendment introduces similar requirements for 767 aeroplanes with Rolls Royce RB211 engines.
