Summary
This action withdraws a supplemental notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to certain Boeing Model 737 series airplanes. That action would have required inspections of certain bonded skin panels to detect delamination of the skin doublers (tear straps) from the skin panels, and follow-on corrective actions if necessary. Since the issuance of the supplemental NPRM, the Federal Aviation Administration (FAA) has issued other rulemaking that requires additional inspections to address the unsafe condition identified in the supplemental NPRM. Accordingly, the supplemental NPRM is withdrawn.
