At 0835 Eastern Standard Time on 26 September 2011, a flight
instructor and student pilot in a Cessna Aircraft Company 152,
registered VH-HCE, was operating at Bankstown Airport, New South
Wales, on a training flight.
After a series of simulated rejected takeoffs, the aircraft
departed runway 11 to conduct circuits. After completion of the
second touch and go, at a height of approximately 200 ft, the
engine gradually lost power. The instructor resumed control, and
with minimal runway remaining, and engine power further reducing,
identified a suitable grassed landing area. The instructor declared
a MAYDAY to air traffic control and positioned the aircraft for an
emergency landing.
After the main wheels contacted the ground, and just prior to
nose wheel contact, the engine power suddenly increased. The
instructor reduced the throttle to idle and continued with the
landing. As the nose wheel contacted the ground it detached, the
aircraft nosed-over and slid a short distance before coming to rest
inverted. The instructor and student vacated the aircraft with no
injuries.
A subsequent inspection identified a quantity of water in the
right fuel tank that probably entered the tank via the right fuel
cap receptacle following a period of heavy rain. Immediately
following the accident the operator conducted a fleet check,
identifying an additional aircraft with water contamination in the
fuel.
As a result of this occurrence, the aircraft operator advised
the ATSB that they were taking the following safety actions:
- Instructor training on fuel system in Cessna aircraft type
operated by the company;
- Student information sessions on water contamination incidents;
and
- Compulsory instructor training.
This accident highlights that following periods of heavy rain,
extra vigilance is needed during pre-flight checks to ensure that
fuel is free of contamination.
