Accomplishment/Instructions
Corrosion
Environmental corrosion (on the external surfaces) is a naturally occurring process which can inevitably affect the continued airworthiness of the engine, engine mounted components and accessories. Susceptibility to corrosion is influenced by a number of factors, including but not limited to, geographical location, season and usage.All general preventive (technical) measures, identification, control and treatment of corrosive attack on aircraft structures and engine materials has to be carried out in accordance with Advisory Circular AC 43-4B from FAA and also in accordance with the information of the aircraft manufacturers Instruction for Continued Airworthiness. Furthermore the preservation procedures for stored and inactive aircraft (engines) provides an effective means for combating and minimizing the corrosion condition and should be adhered to.

Advisory Circular AC 43-4B This advisory circular (AC) is a summary of the current available data regarding identification and treatment of corrosive attack on aircraft structures and engine materials. Corrosion inspection frequency, corrosion identification, and especially corrosion treatment continues to be the responsibility of the operator. These inspections should be accomplished per this AC, the manufacturer’s recommendations, or the operator’s own maintenance program. The procedures in this AC are an acceptable means, but not the only acceptable means, of corrosion treatment. The information in this AC is applicable to aircraft for which the manufacturer has not published corrosion control information.

General recommendation for the storage of spare parts

  1. Ideal storage temperature: 15 25 °C (59 °F 77 °F)
  2. Dry storage (40 60% relative humidity)
  3. UV light-protected storage
  4. Ozone-free storage (no fluorescent light sources, mercury vapor lamps, printers etc.)
  5. Do not store directly on the floor, on walls, in front of radiators or other heat sources
  6. Dust-free storage (use the dust cover)
  7. Rust protection must not be removed (for example the oil film on untreated steel parts or the specially coated packaging materials)
  8. The storage facility will be protected from moisture, swelling agents such as fuels, oils or solvents and corrosive vapors.

ROTAX® genuine spare parts
Shelf life on genuine spare parts does mainly affect parts made of rubber (like hoses, O-rings, oil seals,....). Rubber parts sent from BRP-Rotax GmbH & Co KG have a minimum of 48 months of shelf life beyond the invoice date. For all other parts general storage requirements apply and also the relevant visual checks etc. apply when selling the parts and/or installing the part.
