Why: 14 CFR § 107.165(a)(2)(i) requires a person who produces a small unmanned aircraft to retain the supporting declaration-of-compliance information "for two years after the cessation of production of the small unmanned aircraft system for which the person declared compliance."
Confuses this retention period with the unrelated 1-year lookback used for certificate denial after an alcohol, drug, or cheating offense (§§ 107.57, 107.59, 107.69), which is a different kind of time limit.
Assumes an open-ended retention standard, but § 107.165 sets a specific fixed period (two years after production ceases), not an indefinite "as long as needed" rule.
