Plain English Summary

2/10 complexity

This AD requires owners/operators of specific Gates Learjet Model 35 (SN 35‑001–35‑054) and Model 36 (SN 36‑001–36‑017) to inspect upper wing skin fasteners or perform the Gates Learjet SB 35/36‑57‑1A modification that removes the inspection requirement. Actions must occur within 150 flight hours after 29 Oct 1976 unless already modified. It shifts inspection/modification costs, downtime and parts/labor responsibility to the operators while addressing an airworthiness safety concern.
