FLYING LESSONS suggested by this week's report:

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

Feel free to forward this message for the purpose of pilot education.


** Be extremely cautious about any approach with weather reported or
observed to be near or at minimums. If available weather reports put
the airport below approach minimums, consider diverting elsewhere unless
you are very current and alert, and the airplane is performing
flawlessly. There's no reason a "take a look" approach should be
inherently unsafe, but such an approach requires great attention to
altitude and navigation, and a predisposition toward missing the
approach as the expected outcome unless conditions are just right.

** Reference the final approach glide path angle published on most
instrument approach charts, and compare it to the "normal" 3-degree ILS
glidepath to determine your expected rate of descent inside the FAF.

** Carefully set your altimeter just before flying an instrument
approach, and brief the minimum altitude for the approach including any
adjustments for using remote altimeter settings.

** Apply power before reaching MDA to avoid flying below the lowest safe
altitude while in the process of turning descent into a missed-approach

** A Sunday evening, night approach after a cross-country flight might
entice a pilot into "landing expectation." Beware the hazards of
schedule and mission-fixation ("get-there-itis") when launching on a
trip into challenging conditions.

** There is no excuse for attempting an instrument approach when the
aircraft is not properly equipped and current for the operation.
Attempting a GPS approach using a hand-held GPS, no matter how capable,
is indicative of an overall attitude toward risk management that proves
time and again to be unacceptable for the pilot, his/her passengers,
their families, friends and co-workers, families that might depend on
the pilot for employment, and the overall public view and viability of
personal aviation.

** (Suggested by the continuing "split flap" discussion, below) Delay
extending flaps until all turns are complete and you are wings-level,
especially in the traffic pattern. A roll to the left, especially,
while in a left turn and close to the ground can cause you to lose
precious altitude very quickly, or set you up for a cross-control,
accelerated stall from a relatively low pattern speed in your attempt to
compensate. Multiengine pilots often have difficulty identifying an
engine failure while in a turn, and may mis-interpret a split-flap roll
and yaw with disastrous results close to the ground. Aerobatic pilots
learn quickly to avoid "rolling g's". For different reasons, learn to
avoid "banking flaps". Turn, then wings level, then flaps.

** Gear up and gear collapse mishaps (collectively known as "Landing
Gear-Related Mishaps", or LGRMs) continue to be the most commonly
reported accidents in retractable gear airplanes. For more on factors
commonly correlating with LGRMs and techniques for avoiding gear-related
mishaps, scroll down to the Those Who Won'tT section at <> .

Questions? Comments? Send me a note at


Discussion instigated by the December 31 FLYING LESSONS concerning the
apparent asymmetric flap extension crash of a Beech Duke at Wilmington,
Delaware was one of the most lively we've recently seen. Last week we
had two first-hand accounts of "split flap" incidents, and how the pilot
managed the abnormality. This week we hear from a Bonanza A36 owner who
experienced an asymmetric flap extension, resulting in some FLYING
LESSONS that apply to every flight, and for the first flight after
maintenance. See Split Flaps
<> Bonanza.
This and other "split flap" reports are linked from the bottom of the
Tools for
<> Flying
Safely page of <> .

Thanks, reader, for your input, your expertise and your example of
quality airmanship.


** A Debonair landed gear up..

** A Skipper lost control on landing..

** A[nother] Debonair landed gear up..
