The Piper PA-28 series, which includes the PA-28-235, was certified under CAR, as this aircraft was produced during a time when CAR Part 3 was applicable. This regulation governed the airworthiness standards for light airplanes and was used for many general aviation aircraft produced before the transition to FAR.

In contrast, 14 CFR Part 21 pertains to the certification procedures for products and parts, while 14 CFR Part 23 establishes airworthiness standards for normal, utility, acrobatic, and commuter category aircraft. Since the Piper PA-28-235 predates the implementation of these parts, they would not serve as the correct certification basis for this particular aircraft.
