The FAA has granted an STC to
McCauley Propeller Systems for installation of a new three bladed
propeller for the Beechcraft Baron 95-55, 95-A55, 95-B55, 95-B55A,
and 95-B55B. A new three-bladed STC has also been awarded for the
Cessna E310J, 310J and 310L.
At this time, the majority of Baron 55 and Cessna 310 operators
use older threaded propellers that are heavier and more expensive
to operate. In addition, new replacement blades for threaded
propellers are no longer produced by McCauley. McCauley's
three-bladed BLACKMAC STC propeller will provide operators with an
average weight savings
of 10 pounds when compared to the legacy three-blade propellers
factory installed on these aircraft. In addition, McCauley's Baron
55 and Cessna 310 BLACKMAC STC's offer longer TBOs and fewer ADs
than other propellers available today.
McCauley BLACKMAC STC propellers come with a standard three-year
warranty extended to include McCauley supplied replacement parts
for components found unserviceable due to manufacturing defects at
first recommended overhaul.
Introduced in 1989, McCauley's BLACKMAC STC propellers were
reportedly the first mass production high performance STC propeller
offered to the aviation industry. BLACKMAC STC propellers are
recognized for providing operators with a propeller tailored to
their specific needs. This propeller customization has resulted in
substantial aircraft performance improvements, and has ultimately
led to OEMs adopting BLACKMAC STC designs as their original
factory-equipped propeller. BLACKMAC STC conversions are available
through McCauley's Authorized Service Center Network.
