The FAA is issuing this notice to advise the public of a meeting of RTCA Program Management Committee.

The FAA is issuing this notice to advise the public of the fourteenth meeting of the RTCA Special Committee 227, Standards of Navigation Performance.

The FAA is issuing this notice to advise the public of the fourth meeting of the RTCA Special Committee 231, TAWS-GPWS.

We propose to supersede Airworthiness Directive (AD) 2014-14- 02, which applies to certain Pratt & Whitney Canada Corp. (P&WC) PW120, PW121, PW121A, PW124B, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. AD 2014-14-02 requires removal of the O-ring seal from the fuel manifold fitting. Since we issued AD 2014-14-02, we received reports of fuel seepage past the metal-to-metal sealing surfaces of the fuel nozzle and fuel manifold flow adapter. This proposed AD would require replacement of the fuel nozzle and the fuel manifold flow adapter. We are proposing this AD to prevent in-flight fuel leakage, engine fire, damage to the engine, and damage to the airplane.
