AD: Cessna / Hartzell Engine Technologies

AD NUMBER: 2012-10-52

PRODUCT: Cessna 206, 207, and 210 airplanes with Hartzell Engine Technologies (HET) turbochargers, part numbers (P/Ns) 406610-0005 and 406610-9005, installed.
SUBJECT: Airworthiness Directive 2012-10-52
ACTION: Final Rule, Request For Comments

SUMMARY: This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires removing the affected turbochargers from service before further flight. This AD was prompted by a report of an HET turbocharger causing an engine in-flight power rollback. The FAA is issuing this AD to prevent turbocharger bearing seizure, failed turbocharger components, and damage to the airplane.

DATES: This AD is effective June 26, 2012 to all persons except those persons to whom it was made immediately effective by Emergency AD 2012-10-52, issued on May 14, 2012, which contained the requirements of this amendment. The FAA must receive comments on this AD by July 26, 2012.
