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.
