The "issue" isn't specific to the Learjet model 60. It is a maintenace issue, which is relevant to all business jets & other large airplanes. This has been clearly addressed by the OEM - Bombadier/Learjet. I urge you to acquire & read Bombardier AW 32-046 & AW 32-047. Both of these AWs are public & official record from the OEM that: tire pressures must be checked prior to the first flight of the day and that the effectivity applies to all Learjet models! Thus, per the OEM's guidance, issuance of a tire pressure check AD should apply to, as a minimum, all Learjets. Neither AW has been superceded or cancelled. You are likely aware of additional OEM guidance via AW 32-45, LR60-AFM, LR60- AMM, 60/60XR SMART CARD, plus FAA AC20-97B, Bombardier (AW 32-46) 2.0 INTRODUCTION, states: "This is one element of a strategic effort to promote safety across the entire aviation industry with respect to proper tire inflation."Will the FAA follow suit?
