Plain English Summary

4/10 complexity

This Airworthiness Directive requires operators of aircraft with Rolls‑Royce RB211-524G, -524G‑T, -524H and -524H‑T engines to carry out the initial and repeat thrust‑reverser inspections set out in Rolls Royce Mandatory SB RB.211‑78‑9574 Revision 2. Inspections must start within 700 flight hours of the AD’s effective date and recur no more than every 700 flight hours. CASA says the checks address a risk that incorrect Thrust Reverser Cowl Position (TCRP) resolver rigging could prevent the fuel control cutting back thrust after an in‑flight reverser deployment, so operators bear the inspection cost and scheduling burden to mitigate that safety risk.

For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

AD/RB211/30 Thrust Reverser Inspection 5

AD/RB211/30 Thrust Reverser Inspection 5/2002

Applicability: Rolls Royce RB211-524G, -524G-T, –524H, and –524H-T series engines as identified in Rolls Royce Mandatory SB RB.211-78-9574 Revision 2.

Requirement: Perform initial and repeat inspections as detailed in Rolls Royce Mandatory SB RB.211-78-9574, Revision 2.

Compliance: Within 700 flight hours after the effective date of this Directive and thereafter at intervals not to exceed 700 flight hours.

This Airworthiness Directive becomes effective on 16 May 2002.

Background: The fuel control of the above engines may not cut back thrust in the unlikely event of an in-flight thrust reverser deployment if the Thrust Reverser Cowl Position (TCRP) resolver rigging is less than plus 1 percent on the identified engines. This AD repetitively checks for the correct rigging.
