Analysis
Acft had been repossessed and was being ferried from grand junction, CO, to chicago, IL, with en route stop at Denver, CO. After takeoff from Denver, landing gear would not retract. Plt made several attempts without success. He elected to return to Denver. Plt said that on final apch the right eng began surging and the left eng would not increase pwr. Acft made hard landing on rwy, breaking left wing. Investigation revealed both speed levers would not function because eng prop governors and underspeed fuel governor reset arms, splined onto underspeed fuel governor shafts, were positioned on opposite side of speed lever actuating arms. Landing gear functioned normally during swing tests. It was later learned that right main tire had blown on takeoff 3 days earlier and required repair. Maintenance personnel opened the landing gear circuit breakers to preclude inadvertent gear retraction. Plt said he checked circuit breakers when gear failed to retract.
