The NTSB's report on the accident notes that the Cirrus Pilot's Handbook provides no guidance for turnbacks. Neither do most other handbooks; nobody wants to go that far out on a limb. (The Glasair III handbook, alone among a little stack of miscellaneous POH's that I have, admits that it might under some circumstances be possible to turn back and make the runway.) The NTSB did, however, cite a February 2004 presentation on the subject by a member of the Cirrus Owners and Pilots Association. A successful turnback, the speaker stated, required, prior to the engine failure, a steep climb close to the airport; afterwards, an immediate 45-degree turn into the crosswind while maintaining 80 to 90 knots with no flaps; and then a best-angle glide. One supplemental piece of advice, handy for Cirrus pilots but not for most others, suggested that even this speaker had limited confidence in the maneuver: If less than 500 feet agl remain and the runway is not assured, use the parachute instead.
