Transportation Department, Federal Aviation Administration
The FAA proposes to adopt a new airworthiness directive (AD) for certain MT-Propeller Entwicklung GmbH variable pitch and fixed pitch propellers with serial numbers (SNs) below 95000, which have not been overhauled since April 1994. This proposed AD would require you to perform initial and repetitive visual inspections of those propeller blades. Further, this proposed AD would require you to remove all propeller blades from service with damaged erosion sheath bonding or loose erosion sheaths and to install any missing or damaged polyurethane protective strips. This proposed AD results from reports of stainless steel leading edge erosion sheaths separating from propeller blades and reports of propeller blades missing or without polyurethane protective strips due to insufficient inspection procedures in older MT-Propeller Entwicklung GmbH Operation & Installation Manuals. We are proposing this AD to prevent erosion sheath separation leading to damage of the airplane.
