# Limit of validity.
**AGENCY:**
Federal Aviation Administration, DOT.
**ACTION:**
Final rule; technical amendment; correction.
**SUMMARY:**
The FAA is correcting a technical amendment published May 24, 2012 to a final rule published November 15, 2010. The final rule required design approval holders of certain existing airplanes and all applicants for type certificates of future transport category airplanes to establish a limit of validity of the engineering data that supports the structural maintenance program (hereinafter referred to as LOV). It also required that operators of any affected airplane incorporate the LOV into the maintenance program for that airplane. The technical amendment to the final rule was issued to correct errors, but within its publication, it contained inadvertent errors due to pagination in two tables. This document corrects the errors in those tables.
**DATES:**
This corrective action becomes effective September 7, 2012.

**SUPPLEMENTARY INFORMATION:**
**Background**
On May 24, 2012, the FAA published a technical amendment to a final rule. The technical amendment is entitled “Aging Airplane Program: Widespread Fatigue Damage” (77 FR 30877), which corrected a final rule published November 15, 2010 (75 FR 69746).
In that technical amendment, the FAA intended to correct compliance dates of §§ 26.21, 121.1115, and 129.115 for Airbus A310 and A300-600 series airplanes. Upon publication, however, the technical amendment contained inadvertent errors due to pagination in two of the tables.
Accordingly, FAA amends 14 CFR parts 121 and 129 by making the following technical amendments:
**14 CFR Part 121**
**PART 121—OPERATING REQUIREMENTS: DOMESTIC, FLAG, AND SUPPLEMENTAL OPERATIONS**
1. The authority citation for part 121 continues to read as follows:
