Existing STC Being Offered To Current Operators And New
Owners
Bell Helicopter and Aeronautical Accessories, Inc. are
offering customers substantially better hot-and-high performance
from the Bell 407 through STC# SR095531RC-D, a previously announced
STC now being offered to current operators and new customers at no
cost to them.
"This STC makes the 407 even more effective for our customers by
drawing on the helicopter's design and performance reserves," said
Larry D. Roberts, Bell's senior vice president, Commercial
Business. "All of us at Bell appreciate the business our customers
bring to us and the tremendously important work they do with our
aircraft. Offering these benefits at no additional cost is one way
we can show our appreciation and confirm that purchasing a 407 was
the right decision."
Using the STC, 407 operators can-under specific conditions-boost
their useful load by more than 400 pounds or increase their hover
ceiling by over 3,000 feet. They must adhere to the rotorcraft
flight manual and limit the generator load to less than 50 amps.
(Basic 407 performance charts assume a generator load of 180 amps;
a typical 407 generator load for day operations is 25-30 amps and
35-40 amps at night.) Operators also must perform regular
power-assurance checks per revised procedures to utilize the
performance charts contained in the STC.
The resulting performance gains come with no loss of operational
safety margin, require no hardware or software changes to the
aircraft or its Rolls-Royce M250-C47B engine, and result in no
change to time between overhaul (TBO) or warranty costs (because no
engine limits are changed). Rolls-Royce supports the STC
initiative.
The STC is available now as a retrofit through Aeronautical
Accessories in Piney Flats, Penn. Contact Keith Ray, AAI sales
manager, 423-391-3607. For new 407s delivered from Bell Helicopter
Textron Canada Ltd.'s plant in Mirabel, Quebec, the STC will be
included with the aircraft.
Revised performance charts are available under the STC for both
the basic 407 inlet configuration and for the BHT-407-FMS-3
Particle Separator Kit.
