only. Fresh water condensation does far less damage than entrapped salt spray. In emergencies where regular waterproof canvas covers are not available, use a polyethylene sheet, polyethylene-coated cloth, or metal foil barrier materials as covers and shrouds. Hold these covers in place with adhesive tape that is designed specifically for severe outdoor applications. GROUND HANDLING REQUIREMENTS The MIM for an aircraft usually describe brief and simple ground-handling procedures. When followed, these procedures reduce corrosive attack. These procedures keep water, salt, and dirt out of areas that are difficult to get at and easy to overlook. As you can see, they also save a tremendous amount of maintenance work later. Many practices, when followed, lessen paint damage and the loss of built-in protective systems during normal ground handling of the aircraft. Some of these practices are listed below. Use the tie-down points provided. Much damage is done to aircraft paint films by failure to use the tie-down points or by passing tie-down cables and lines over or around supporting structures so the paint finish is worn, chipped, or broken. Take time to wipe or brush sand or gravel from shoe soles before climbing on the aircraft. Painted aircraft surfaces will withstand a normal amount of foot traffic and abrasion by fuel hoses and air lines. However, shoe soles and fuel hoses pick up bits of sand, gravel, and metal chips. These become a coarse abrasive that scratches and scuffs the protective finish so it is completely ineffective under shipboard operating conditions. Do not place removed hardware on the deck. When you remove cowling and access plates during inspections and you cannot provide pads or cushions for them, secure them to prevent their movement. Avoid scratching the paint when you use hand tools to remove screws and quick-opening fasteners on aircraft exteriors. As little as 5 minutes of extra time spent carefully using tools might save hours of paint touch-up and corrosion removal. Q32. Why should dry-cleaning solvent not be used in oxygen areas or around oxygen equipment? Q33. In emergencies when regular waterproof canvas covers are not available, what materials can you use as covers and shrouds? Q34. The ground handling requirements for an aircraft can be found in what publication? RECOVERY AND RECLAMATION OF CRASH DAMAGED AIRCRAFT LEARNING OBJECTIVE: Identify publications used to describe emergency reclamation procedures. General procedures are required anytime an aircraft is exposed to gross amounts of saltwater or fire-extinguishing agents. Each activity that is assigned custody of aircraft has a recovery and reclamation team. The size and composition of the team depend upon the urgency of the situation. As a maintenance crew member, you may be called upon to assist with reclamation of an aircraft. Recovery and reclamation procedures are covered in detail in NAVAIR 01-1A-509. Methods for cleaning support equipment (SE) are different from those used to clean aircraft. Authorized SE cleaning materials and procedures are identified in Ground Support Equipment Cleaning and Corrosion Control, NAVAIR 17-1-125. Q35. What technical publication covers emergency reclamation procedures for naval aircraft? LEVELS OF AIRCRAFT PRESERVATION LEARNING OBJECTIVES: Describe the levels of aircraft and engine preservation. Identify the preservatives and sealants used in the preservation of aircraft and support equipment. The exposure of an aircraft to corrosion damage is greatest when the aircraft is dirty, inactive, or being shipped. Aircraft spend more time on the ground than in the air, even in an active squadron. Therefore, they must be effectively protected. The method of preservation is based on complexity of the aircraft. A variety of methods are used to preserve aircraft. Preservation applies to all types of naval aircraft. There are three different levels of preservation used on naval aircraft: 4-15
