The certificate holder must make available to the Administrator each airplane for which an inspection and records review is required under this section, in a condition for inspection specified by the Administrator, together with records containing the following information:

(1)

Total years in service of the airplane;

(2)

Total time in service of the airframe;

(3)

Total flight cycles of the airframe;

(4)

Date of the last inspection and records review required by this section;

(5)

Current status of life-limited parts of the airframe;

(6)

Time since the last overhaul of all structural components required to be overhauled on a specific time basis;

(7)

Current inspection status of the airplane, including the time since the last inspection required by the inspection program under which the airplane is maintained;

(8)

Current status of applicable airworthiness directives, including the date and methods of compliance, and if the airworthiness directive involves recurring action, the time and date when the next action is required;

(9)

A list of major structural alterations; and

(10)
