AD: Engine Alliance Turbofan Engines

AD NUMBER: 2013-02-06

PRODUCT: All Engine Alliance GP7270 and GP7277 turbofan engines.
SUBJECT: Airworthiness Directive 2013-02-06
ACTION: Final Rule, Request for Comments

SUMMARY: This AD requires initial and repetitive borescope inspections and removal from service before further flight if one or more burn holes are detected, in certain highpressure turbine (HPT) stage 2 nozzles. This AD also requires mandatory removal from service of these HPT stage 2 nozzles at the next engine shop visit. This AD was prompted by a report received of inadequate cooling of the HPT stage 2 nozzle, leading to damage to the HPT stage 2 nozzle, burnthrough of the turbine case, and engine shutdown. The FAA is issuing this AD to prevent HPT stage 2 nozzle failure, leading to uncontrolled fire, engine shutdown, and damage to the airplane.

DATES: This AD is effective February 12, 2013. Comments on the AD must be received by March 14, 2013.
