Content, form, and disposition of maintenance, preventive maintenance, rebuilding, and alteration records (except inspections performed in accordance with part 91, part 125, § 135.411(a)(1), and § 135.419 of this chapter)

In plain English

When maintenance or preventive maintenance is done, a record entry is required: a description of the work, the date completed, the name of the person doing it, and the signature and certificate number of the person approving it for return to service.

Key points

• Record: description, date, name, and the approver’s signature + certificate number.
• Applies to both maintenance and preventive maintenance.
• Inspections use 43.11 instead.

Common pitfalls

• Vague or unsigned entries that won’t hold up at an annual or sale.
