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.

-- Any abnormal indications should be checked by a mechanic. Even if indications cease momentarily, the underlying reasons may lead to a a mishap.

-- There is a identifiable correlation between dual instruction and landing gear-related mishaps (LGRMs).

-- Instruction by its nature introduces distractions to the pilot, making gear omissions more likely. Instruction flights are more likely to include touch-and-go landings, another strong correlative factor for LGRMs. Further, some students alter their normal habit patterns when flying with an instructor.

-- There is also a correlation between strong or gusty surface winds and gear-up landings.

-- Shoulder harness installation should be at the very top of an airplane owner’s priority list if the airplane does not already have them installed. All aircraft occupants should wear shoulder harnesses at all times—emergencies happen quickly, leaving little time for attaching shoulder harnesses if they were not already being worn.

-- Even “minor” damage involving a gear collapse in a twin-engine airplane typically results in $60,000+ in repair cost, according to the insurance industry.

-- For extensive data and commentary on landing gear-related mishaps (LGRMs) in all makes and models of certified, piston RG airplanes, go to and scroll down to the LGRM section.

-- For more data and analysis on LGRMs see the LGRM pages of
