AD: General Electric Company Turbofan Engines

AD NUMBER: 2013-06-06

PRODUCT: General Electric Company (GE) CF34-8C and CF34-8E turbofan engines with certain part numbers (P/N) of operability bleed valves (OBV) installed.
SUBJECT: Airworthiness Directive 2013-06-06
ACTION: Final Rule

SUMMARY: This AD was prompted by three failure events of ring lock fuel fittings on the OBV. Two of those events led to an engine fire. This AD requires the affected OBVs be removed from service and replaced with OBVs eligible for installation. We are issuing this AD to prevent failure of OBV ring lock fuel fittings, engine fuel leakage, uncontrolled fire, and damage to the airplane.

DATES: This AD is effective May 8, 2013.
