3. Life Limited Parts Marking and Disposition
14 CFR Part 43.10, Disposition of Life-Limited Aircraft Parts requires that proper procedures are
followed when removing life limited parts with time and/or cycles remaining on them as well as the
disposition of life limited parts with no time and/or cycles left. Life limited parts defined by Type
Certificate (TC) are listed in paragraph 1, above. Other parts which are replaced or rebuilt at
specified intervals are listed in Chart 2, above, and in 5-20-00 and 5-50-00.
A. Parts that are removed prior to accumulating their life limit, are to be marked with indelible ink
or marker with the part number, serial number and accumulated life status as defined in 14
CFR Part 43.10 in a manner that does not affect part structural integrity, i.e. - no surface
deformation such as vibration/etching allowed.
B. Parts that have accumulated the life limit shall be disposed of in accordance with the
applicable FARs. Piper recommends life limited parts with no time and/or cycles remaining be
completely destroyed.
