Can someone help with required logbook entry after a “major change” autopilot addition that required a 5-hour phase 1 test period per local FSDO. The following is what my operating limitations say, and entering the weight and stall speed seems reasonable, but do I really need to do a full set of climb tests to recalculate Vx and Vy even though the autopilot addition has no significant impact on these numbers? If not, do I just use the numbers calculated for and noted in my original phase 1 entry?
Thanks.
[”After incorporating a major change as described in § 21.93, the aircraft owner is required to reestablish compliance with § 91.319(b) and notify the geographically responsible FSDO of the location of the proposed test area. The aircraft owner must obtain concurrence from the FSDO as to the suitability of the proposed test area. If the major change includes installing a different type of engine (reciprocating to turbine) or a change of a fixed-pitch from or to a controllable propeller, the aircraft owner must fill out a revised From 8130-6 to update the aircraft’s file in the FAA Aircraft Registry. All operations must be conducted under day VFR conditions in a sparsely populated area. The aircraft must remain in flight test for a minimum of five (5) hours. The FDSO may require additional time (more than 5 hours) depending on the extent of the modification. Person's nonessential to the flight must not be carried. The aircraft owner must make a detailed logbook entry describing the change before the test flight. Following satisfactory completion of the required number of flight hours in the flight test area, the pilot must certify in the records that the aircraft has been shown to comply with § 91.319(b). Compliance with 91.319 (b) must be recorded in the aircraft records with the following or similarly worded statement: "I certify that the prescribed flight test hours have been completed and the aircraft is controllable throughout its normal range of speeds and throughout all maneuvers to be executed, has no hazardous characteristics or design features, and is safe for operation. The following aircraft operating data has been demonstrated during the flight testing: speeds Vso_______, Vx________, and Vy_________, and the weight________, and CG location_______ at which they were obtained".
