FAA: "Aircraft Engine Built with Auto Parts Gains FAA Certification"

The FAA used the 2003 AOPA Expo to crow about another development... one that they seem to be taking some credit for, even though their creative involvement was limited to whatever it took to prove that the device complied with certification protocols. FAA Administator Blakey, herself, announced the US certification of an "innovative diesel aircraft engine that uses automotive parts and runs on jet fuel."

The 4 cylinder, 135 hp TAE 125-01, made by German-based Thielert Aircraft Engines (TAE), is the product of an auto racing engine and global automotive parts manufacturer. This newly certified aircraft engine can be installed in general aviation aircraft such as two-seat Cessna and Piper models. TAE assembles the engines using Daimler Chrysler auto parts that have been evaluated against the company's strict criteria. The engine is then combined with a gearbox and other parts produced by TAE.

"The FAA's goal is to bring new technologies and equipment into the U.S. aviation system as soon as we are assured of their safety and benefits," said Administrator Blakey. "With some modification and ingenuity, we have an engine that has gone from the pavement to the sky."

Before granting a type certificate to the TAE-125-01 engine, the FAA ensured the company's quality control approach guarantees that each part conforms to the type design and upholds an acceptable safety level. TAE analyzes potential failures and effects for all Daimler Chrysler parts. The firm validates that each part meets design requirements through a "check plan" that details those requirements. TAE also has tested one engine to destruction to confirm the design, and conducts a fill engine endurance test as a standard for each engine lot.

Based on certification tests for the TAE 125-01, the FAA specifies a life limit of 1000 hours or 12 years, whichever comes frst. Overhaul is not allowed and owners must replace the engine after the time limit, Also, as jet fuel becomes more available at smaller airports around the country, the engine provides another powerplant option for the general aviation community.
