IPL (Inspection Parts List). These are used when
assembling the aircraft. Each aircraft section has an IPL. PRINT the IPL's as
you build the aircraft. Each time you install a part, initial the IPL so that
you have a record of the part, as installed. Once you are completed an IPL,
sign off the section or even better, get someone else to sigh it of. Two sets
of eyes is better than one!
