The July 19, 2007 Weekly Accident Update is now posted at

own sake, but to improve safety by preventing [future] accidents." - Air

FLYING LESSONS suggested by this week's report

Although based on Beech mishap records, the lessons learned are
universal. Consider how they may apply to the airplanes you fly.

-- Distraction, often from another airplane behaving unexpectedly in the
traffic pattern, is commonly mentioned in reports of gear up landings.
See or hear another airplane? Double-check your landing gear position.

-- Although many landing gear collapse mishaps result from inadvertent
retraction commanded by the pilot, talking with mechanics and parts
suppliers has me convinced that maintenance issues are a major factor in
many gear collapse events. Bent pushrods, failed rod ends, weak gear
motors and hydraulic pumps, and things as simple as worn bushings or
missing springs can prevent full gear extension or cause the gear to
during the takeoff or landing roll. Proactive replacement or overhaul of
landing gear components, bushings and hardware on condition or per the
manufacturer's recommendations (whichever comes first) may seem
expensive, but given that a gear collapse routinely costs $40,000 to
$60,000 to repair, often "totaling" an airplane, proactive gear
maintenance and overhaul is indeed "cheap insurance."

Many of you will be flying to Oshkosh this week. Some of you may
already be en route right now. Arriving at AirVenture is extremely
distracting, and all the excitement invites both show-offmanship and
get-there-itis. Don't forget that these distractions affect Oshkosh
departures as well. Every year we read accounts of unfortunate pilots
who crash getting to, arriving at, departing or flying home from the
Greatest Airshow on Earth. It's not too late for a last-minute review
before that last leg into KOSH. To help, here are links to articles
from my 2006 series on Flying to AirVenture:
