JET A NOZZLES have a duckbill design that should not fit into the restricted-size fueling port
of a piston aircraft.
ON MARCH 2, 2008, a turbonormalized
Cirrus SR22 was destroyed when
it crashed shortly after takeoff in Rio
de Janeiro, Brazil, killing all four people
aboard. Shortly after the aircraft
departed from Runway 20, the engine lost
power, and the airplane hit a building and
exploded. Further investigation revealed
that the aircraft had been refueled with
Jet A instead of 100LL.
On April 17, 2015, a Cessna 421B crashlanded
on a highway shortly after takeoff
from Lufkin, Texas, resulting in one serious
and two minor injuries. According to
the pilot, the aircraft seemed to perform
normally during the runup, takeoff, and
initial climb. Passing 2,100 feet agl, the
96 | AOPA PILOT July 2021
left engine sputtered and lost all power.
Within 30 seconds, the right engine also
lost all power and the big cabin-class twin
descended for a forced landing. The airplane
landed hard, damaging the wings
and fuselage and rupturing the right fuel
tank, finally coming to rest in the grassy
median of a highway. The smell of jet
fuel was prominent at the accident scene.
Investigators found that the FBO's Jet A
truck had recently had its wide duckbillstyle
nozzle replaced with a slim round
nozzle, and that the 421B did not have the
fueling port restrictor rings installed per
airworthiness directive 87-21-02 despite
maintenance logs indicating the AD had
been complied with.
