A quick hole repair method comprises steps as follows: firstly, a plugging cover matched with a to-be-repaired hole is produced from a nylon material according to the diameter of the to-be-repaired hole, the plugging cover comprises a hole plugging part, a hole clamping part and a clamping part, then the plugging cover extends into the to-be-repaired hole to be mounted on a structure of the to-be-repaired hole, the hole plugging part is plugged at the upper part of the structure of the to-be-repaired hole, the hole clamping part is clamped in the middle of the to-be-repaired hole, and the clamping part is fixed at the bottom of the structure of the to-be-repaired hole; finally, paint is sprayed on outer surfaces of the plugging cover and the repaired structure of the to-be-repaired hole, and thus the extra hole is repaired. The plugging cover is simple to produce, convenient to mount, higher in reliability, lower in cost, better in practicability, saves time and labor, can be widely applied to change and repair of parts of aircraft systems at the scientific research stage and has higher practical value, and waste is avoided while the safety is guaranteed.
