Airworthiness Directives

Airworthiness Directives (AD) are legally enforceable rules issued by the FAA in accordance with 14 CFR part 39 to correct an unsafe condition in an aircraft, aircraft engine, propeller, or appliance.

The FAA Aircraft Certification Service determines the need for an Airworthiness Directive. The Certification Service has twelve Aircraft Certification Offices (ACO) within four Directorates assigned by type of product: Transport Category Airplanes, Small Airplanes, Rotorcraft, or Engines and Propellers.

Aviation Safety Engineers (ASEs) in the Directorate staff monitor assigned products to determine unsafe conditions and the need for ADs. When an unsafe condition exists, the Directorate responsible for the product will draft, coordinate, and issue ADs based on information provided by an ACO or Directorate Standards Staff.

The Type Certificate owner is responsible for notifying the FAA when they become aware of any failure, malfunction, or defect in any product, part, process, or article manufactured by them. They are also tasked with developing appropriate design changes to correct the unsafe condition and incorporating the corrective action in future production of the product to ensure the product is in condition for safe operation.

Aircraft owners and operators are responsible for ensuring compliance with the requirements of all ADs that apply to their aircraft. Anyone who operates a product that does not meet the requirements of an applicable AD is in violation of 14 CFR 39.7.

No person may operate a product to which an AD applies, except in accordance with the requirements of the AD. Furthermore, the owner or operator of an aircraft is required by FAR 91.403 to maintain their aircraft in compliance with all ADs.

Alternative Method of Compliance (AMOC)

Different approaches or techniques that are not specified in an AD can, after FAA approval, be used to correct an unsafe condition on an aircraft or aircraft product. Although the alternative may not have been known at the time the AD was issued, an alternative method could be acceptable to accomplish the intent of the AD. A compliance time that differs from the requirements of the AD can also be approved if the revised time provides an acceptable level of safety that is at least equivalent to that of the requirements of the AD.

Airworthiness Directives Listing

The list below, and posted separately on the linked pages, are all of the aircraft, engine, and propeller ADs pertinent to the Cessna 150 and 152.

Appliance ADs are not listed. Since the fleet is several decades old, and most have been changed and modified several times since they left the factory, we have no idea what you have installed in your airplane and cannot possibly list all of the appliance ADs. You’re on you own there.
