It is a very important ability whether civil aircraft allows the towing operation when tires flat in actual operating. Based on a certain type of regional aircraft, associating with ground load, ground equipment, landing gear structure, weight balance and maintenance engineering specialty etc, this paper studies the related airworthiness clauses of towing with deflated tires, analyzes the towing load of a certain type of aircraft and defines the scene when towing with deflated tires occur. Procedures of the normal towing and deflation towing are analyzed and similarities and differences of competing types of aircraft are also compared. On this basis, the actual towing ability of a certain type of aircraft is evaluated and more research on weight, safety factor of towbar and other aspects is conducted. Finally, the conclusion is provided that this type of aircraft has towing ability with single deflated tire by exceeding 60% of load requirement of the clause and being confirmed by strength evaluation.
