When are aircraft maintenance records required?
Whenever any maintenance, preventive maintenance, rebuilding, or alteration is performed.Maintenance means inspection, overhaul, repair, preservation, and the replacement of parts (excludes preventive maintenance).In other words, you must make a record entry for everything, including tire changes.

14 CFR 43.5Approval for return to service after maintenance, preventive maintenance, rebuilding, or alteration.
No person may approve for return to service any aircraft, airframe, aircraft engine, propeller, or appliance, that has undergone maintenance, preventive maintenance, rebuilding, or alteration unless(a) The maintenance record entry required by 43.9 or 43.11, as appropriate, has been made; (b) The repair or alteration form authorized by or furnished by the Administrator has been executed in a manner prescribed by the Administrator; and (c) If a repair or an alteration results in any change in the aircraft operating limitations or flight data contained in the approved aircraft flight manual, those operating limitations or flight data are appropriately revised and set forth as prescribed in 91.9 of this chapter.

91.405Maintenance required.
Each owner or operator of an aircraft(a) Shall have that aircraft inspected as prescribed in subpart E of this part and shall between required inspections, except as provided in paragraph (c) of this section, have discrepancies repaired as prescribed in part 43 of this chapter;(b) Shall ensure that maintenance personnel make appropriate entries in the aircraft maintenance records indicating the aircraft has been approved for return to service; (c) Shall have any inoperative instrument or item of equipment, permitted to be inoperative by 91.213(d)(2) of this part, repaired, replaced, removed, or inspected at the next required inspection; and (d) When listed discrepancies include inoperative instruments or equipment, shall ensure that a placard has been installed as required by 43.11 of this chapter.

ADVISORY CIRCULAR 43-9B
Maintenance records are a shared responsibility between the owner/operator and maintenance personnel, with the ultimate responsibility resting with the owner/operator.

FAR 43.9
RECORD ENTRIES
Maintenance Records (except for inspections) shall contain the following information:

A description (or reference to data) of work performed.The date of completion of the work.The name of the person performing the work if other than specified below.The signature, certificate number, and kind of certificate held by the person approving the work.

DESCRIPTION OF WORK PERFORMED
The description should be in sufficient detail to permit a person unfamiliar with the work to understand what was done, and the methods and procedures used in doing it.

INCORPORATION BY REFERENCE
You dont have to write a book.The rule permits reference to technical data in lieu of making a detailed entry.Common references include maintenance manuals, service letters, bulletins, work orders, advisory circulars (AC43.13-1B), and others.Major alterations may reference STCs.\Reference documents must be retained.

IN ADDITION
major repairs and alterations shall be entered on a form, and the form disposed of, in a manner prescribed in appendix B, by the person performing the work.Requirements of appendix B have changed! You will soon be able to file online.

14 CFR 43.11, RECORDS FOR INSPECTIONS

______________________ ______________________________________

Signature Certificate # Date

Other Considerations
If you find the aircraft to be unairworthy, you need to list the discrepancies. The list must be signed and dated.For progressive inspections, the certification statement is different.For other approved inspection programs, the entry is made according to that program.

FAR 91.417 (a) MAINTENANCE RECORDS
The owner/operator shall keep the following records:
Aircraft Logbook

Records of the maintenance, preventive maintenance, alterations, 100 hour, annual, progressive and other required or approved inspections, as appropriate.Total time in service for the aircraft, each engine, each propeller, and each rotor.Current status of life-limited parts.Time since last required overhauls.

The current status of applicable Airworthiness Directives (A.D.)Copies of FAA Form 337 for any major alterations performed.

14 CFR 91.417 (b)(1)

The Owner or Operator shall retain all maintenance records for 1 year after the work is performed or until the work is repeated or superseded by other work.

FAR 91.417 (b)(2)
After one year, some maintenance records do not have to be retained.For the most part, this pertains to repairs and replacement of parts that are not life-limited.Altimeter/Transponder checks must be kept for 24 calendar months, or until repeated.All other records must be retained and transferred with the aircraft at the time the aircraft is sold.

Lets talk about A.D.s
The owner/operator shall keep records containing the current status of applicable airworthiness directives (AD) including, for each, the method of compliance, the AD number, and revision date. If the AD involves recurring action, the time and date when the next action is required.

Breaking this down .
How do you determine the current status?What was the method of compliance?Do you enter the revision date?For recurring ADs, do you enter the time and date of next recurring action?Where do you make these entries?
