Title:Nose Gear Towbarless Tow Vehicle Basic Test Requirements
Issuing Committee:Age-2c Vehicle Maintenance And Aircraft Servicing Committee
Scope: The purpose of this specification is to provide airplane operators and tow vehicle manufacturers with: A. General design and operating requirements pertinent to test and evaluation of towbarless tow vehicles. Specific design requirements are provided in ARP4852A and ARP4853A. B. Test and evaluation requirements. The results of these test evaluations will determine if the loads induced by the tow vehicle will exceed the design loads of the nose gear, reduce the certified safe life limit of the nose gear, or induce a stability problem during pushback and/or maintenance towing operations.
