LearJet 60XR Sold

Sky Aircraft Holdings Founder Tom Conlan, coordinated the transaction. The Lear 60XR was delivered with a fresh Engine Low Utilization Inspection (LUI), a fresh pre-purchase inspection inclusive of fresh “A” & “B” inspections, and new interior carpeting.

What does it mean to have a Low Utilization Inspection? LUI’s are dependent on the type of engine and do not apply to all engines. LUI requirements are found in the OEM’s Engine Maintenance Manual. In this case, a low utilization engine is defined as an engine that has not been subject to disassembly and inspection of both hot section and cold section at an approved overhaul facility by the end of the service intervals. The LUI inspection program timeframe depends on the manufacturer. Each engine manufacturer outlines their engine inspection requirements in their manual.  An example of an engine inspection might include visual inspection for corrosion of structural cases and ducts, an inspection of the electrical connectors, oil quality checks, and a borescope inspection of the compressor, diffuser, combustor, and turbine. If the inspection is satisfactory, the continued operation of the engine can continue for a certain period of months before repeating the inspection.

The Pre-Buy Inspection was completed by Standard Aero. The purpose of the pre-buy inspection is to confirm the integrity of the aircraft and its documentation. Buyer’s hire qualified Maintenance, Repair and Operations (MRO) facilities to thoroughly inspect the aircraft and provide an unbiased report of aircraft airworthiness.  An aircraft pre-buy inspection typically includes documentation review, airframe inspection, avionics inspection, interior and equipment inspections, and an engine inspection. 

The pre-purchase inspection was inclusive of both A and B inspections. Just like an LUI, A & B inspections are carried through based on the engine manufacturer’s requirements written in the OEM’s engine manual. The inspections include a variety of checklists. For example, the MRO may perform an interior and aircraft-hull inspection for signs of damage, deformation, corrosion, and missing components. It may include inspecting emergency lights, lubricating the nose gear retract actuator, and checking parking brake accumulator pressure. The checklists are outlined in the engine manual for the MROs to follow closely to ensure everything is done precisely.
