### TITLE: POWER PLANT - INSPECTION AND TORQUE CHECK OF PRATT & WHITNEY ENGINE FORWARD MOUNT BOLTS **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES The MP159 material forward mount pylon Bolts, PN 51U615, that replaced Inconel 718 material bolts to improve bolt fatigue life short-falls do not achieve the desired full inspection interval of 8,000 flight cycles. The MP159 material forward mount pylon bolt and nut are more durable and have significant life improvements relative to the Inconel 718 material bolt. However, the MP159 forward mount pylon bolt still does not achieve the required 8,000 flight cycles inspection interval in a bolt-out condition. A torque check has been introduced trough the Pratt & Whitney Service Bulletin No. PWG4-100-A71-32 initial issue. This Service Bulletin is published to advise operators of A330 aircraft equipped with Pratt & Whitney engines of a new issue of Pratt & Whitney Service Bulletin No. PWG4-100-A71-32. The purpose of the Service Bulletin is to provide repetitive inspection procedures and intervals for engines with the MP159 material forward mount pylon Bolts, PN 51U615, to check the torque of the FWD mount pylon bolts (4 positions). Accomplishment of this Service Bulletin will ensure the structural integrity of the MP159 material forward mount pylon Bolts. Extended mission lengths of the passenger variant of A330 aircraft and new flight loads for the freighter variant of A330 aircraft have been taken into account for threshold and interval linked to the Extended Service Goal (ESG) part A.
