Plain English Summary

3/10 complexity

Operators of Airbus A320-100/200 aircraft with Garrett APU GTCP36-300 (P/N 3800278-2) must complete the work in Garrett Service Bulletin GTCP36-49-6549 by 2 April 1995, except for specified serial-numbered or previously modified units. The measure—mandated by CASA—adds a secondary containment shield after a turbine rotor separation was seen in a Garrett bench test. Operators (or their MROs) bear parts, labour and downtime costs and must verify serials/modification status to determine applicability.
