Checklist and operating flow
The Lear 55 checklist (Rev. 3/26/2004) is a PNF/PF list. It runs from start through taxi, line up, climb (FL 180), cruise, descent, approach, landing and shutdown. For a go-around it calls for: autopilot disengaged, flaps 8 degrees, gear retracted at positive rate, then climb at approach speed and flaps up at Vref + 30.
Wheels and brakes parts
The main wheel assembly is part 5004913. It has several dash-number versions, and some were added by service bulletins Lear 55-32-3, 55-32-4 and 55-32-5. The Aviall catalog marks some items as not procurable, to be used until stock depletion. The same wheel is listed for Learjet 23, 24, 25, 31, 35, 36, 55 and 56.
Divan modification (STC ST01580WI)
ICA AF-487 Rev A (July 14, 2011) covers 2-place side-facing divans on Learjet models 55, 55B, 55C and 60. Inspect the upholstery, belts, fittings and frame every 300 hours or 12 months. The ICA lists no additional overhaul limits and no airworthiness limitations for the divan installation.
