The September 13, 2007 Weekly Accident Update is now posted at

This week's report encompasses the two-week period August 30 - September

FLYING LESSONS suggested by this week's report:

Lessons learned from Beech experience are universal. Consider them in
any make and model of airplane.

** If you know "an accident waiting to happen," intervene for safety if
at all possible. Don't be shy about offering to orient a new pilot to
local procedures.

** "Hot" and "heavy" don't mix-a recurring theme in this week's report.

** Any combination of high operating weights, hot temperatures, uphill
takeoff and/or rising terrain make a flight a disaster before the pilot
and passengers ever climb aboard.

** Gear up landings can happen to anyone, even someone who has owned the
same airplane for 30 years.

** Prioritize shoulder harness installation above merely nice-to-have
items like avionics.

** Avoid being rushed when preparing to fly. If you catch yourself
taking shortcuts or getting impatient, slow down and consider the
possible consequences of your actions.

** Compute weight and balance and runway requirements for every flight,
unless you're already familiar with the characteristics of the airplane
under very similar conditions and can confirm without reservations that
all operation is within safe margins.

** Follow standard procedures. Check the Airport/Facilities Directory
and local knowledge if you're unfamiliar with the airport or route.

** Inspect for an obstructed landing gear emergency extension handcrank
whenever accepting the airplane after any inspection, maintenance or
repair that might even remotely require removing the carry-thru spar

** It's become popular to intentionally exhaust all fuel from the tanks
to eke out the greatest possible range. If you run all but one tank
dry, however, you run the risk that fuel in your one remaining tank may
become unusable for some reason and you no longer have the redundancy of
multiple tanks. Miscalculation of fuel loading or fuel burn, a loose or
leaky fuel cap seal, blocked fuel vents and bunched or collapsed fuel
bladders are just a few examples of scenarios that can make fuel in any
one tank unexpectedly unusable.

** A heavily loaded A36 crashed on departure in hot temperatures..

** A V35B landed gear up..

** A B33 experienced partial power loss after takeoff..

** A heavily loaded A36 was unable to outclimb mountainous terrain..

** A B35 crashed into a house..

** An A36 pilot experienced electrical failure, only to find his landing
gear handcrank inaccessible..

** An F33A's nose gear collapsed on landing..

** An A36's left main gear collapsed on landing..

** The nose gear of an H18 collapsed on landing..

** An F33A porpoised, had a prop strike, and collapsed the nose gear on

** A B55 landed long..

** An H35's nose gear collapsed on landing..

There is also an NTSB preliminary report on a Model 36 engine stoppage
after intentionally draining all but one fuel tank dry, and updates on
the Baron fire at Chamblee, Georgia and the Sierra crash while "heavy
and hot" at Niceville, Florida.
