BLR Aerospace - STC Expands Performance
Options For Bell 204/250 Operators
BLR Aerospace has good news for
owners and operators of Bell 204, 205A,
205A1, and 205B helicopters — especially
those whose aircraft are already equipped
with Dual Tailboom Strakes. The
FastFin™ segment of the FastFin tail rotor
enhancement and stability system has re-
ceived Supplemental Type Certification
from the Federal Aviation Administration
for installation on these Bell aircraft.
“Operators, especially those who do
utility work, can now realize the full ben-
efits of the FastFin tail rotor enhancement
and stability system,” said Dave Marone,
Vice President of Sales and Marketing for mountainous Afghanistan. investments.”

tivity and safety while reducing workload
for helicopter operators. FastFin also ex-
pands lifting capacity and performance
while enabling greater stability in all flight
regimes. Installation of the system will
improve hot/high performance while in
power-limited conditions by up to 4.5 per-
cent and reduce fuel burn in hover by up
to 6.5 percent. When in a left pedal-lim-
ited condition, performance results can be
significantly greater.
The patented FastFin System modifies
the tailboom with two parallel stall strips
(Dual Tailboom Strakes) and a re-shaped
vertical fin, optimizing airflow around the
tailboom for dramatically improved han-
dling. As a result of the new STC, opera-
tors may purchase kits for the vertical fin
alteration. Kits for the entire FastFin mod-
ification (with the Dual Tailboom Strakes)
are also available.
FastFin is available for Bell 212s and
most UH-1 derivatives. BLR has a certi-
fied Dual Tailboom Strake System for the
Bell 412 and is hopeful to certify the Bell
412 FastFin System in early 2010. The
U.S. State Department has installed
FastFin systems on 10 Bell HUEY-II he-
licopters operating in Afghanistan. The
enhancement helps the armed aircraft fly
more effectively with greater payloads at
high density altitudes, making it an ideal
addition for aircraft operating in hot,
