AD 2012-10-52

May 18, 2012

This emergency AD was prompted by a report of an HET turbocharger causing an engine inflight power rollback. Upon investigation, the turbocharger was found to have incorrectly located oil passages in the center housing, causing insufficient oil flow to the bearings. This condition, if not corrected, could result in turbocharger bearing seizure, failure of the turbocharger turbine shaft or wheel, and damage to the airplane.
