The incorrectly specified reference was Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D622N001-9, Revision October 2018, which did not include reference to Subsection B. The correct reference is Subsection B., “Airworthiness Limitations—Structural Inspections,” of Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D622N001-9, Revision October 2018. ### Related Service Information Under 1 CFR Part 51 The FAA reviewed Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs), D622N001-9, Revision October 2018. This service information describes procedures for airworthiness limitations for structural inspections, fuel tank systems, safe life limits, and certification maintenance requirements. This AD also requires the following service information, which the Director of the Federal Register approved for incorporation by reference as of June 30, 2006 (71 FR 30278, May 26, 2006). • Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, “Airworthiness Limitations and Certification Maintenance Requirements,” Subsection B. of Boeing Document D622N001-9, Revision “May 2003.” • Boeing 757 Maintenance Planning Data (MPD) Document, Section 9, “Airworthiness Limitations and Certification Maintenance Requirements,” Subsection B. of Boeing Document D622N001-9, Revision “June 2005.” This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. ### Correction of Publication This document corrects an error and correctly adds the AD as an amendment to 14 CFR 39.13. Although no other part of the preamble or regulatory information has been corrected, we are publishing the entire rule in the Federal Register. The effective date of this AD remains March 5, 2020. Since this action only corrects the service information reference for revising the existing maintenance or inspection program specified in the regulatory text, it has no adverse economic impact and imposes no additional burden on any person. Therefore, the FAA has determined that notice and public comment procedures are unnecessary. ### Adoption of the Correction Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: ## Affected data sheets (1) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A2NM](https://openairdocs.org/tcds/A2NM): The Boeing Company; names 4 of 4 models: 757-200CB Series, 757-200PF Series, 757-300 Series, 757-200 Series ## Registered aircraft it may apply to (OpenAirDocs) Matched by airframe and engine model; the AD's applicability may narrow it by serial number, part number or equipment. - Aircraft: 270 (270 by airframe model, 0 by engine model) - Makers: Boeing 270 Models with the most aircraft: - [Boeing 757-232](https://openairdocs.org/model/boeing-757-232): 63 aircraft (airframe model) - [Boeing 757-224](https://openairdocs.org/model/boeing-757-224): 40 aircraft (airframe model) - [Boeing 757-222](https://openairdocs.org/model/boeing-757-222): 38 aircraft (airframe model) - [Boeing 757-223](https://openairdocs.org/model/boeing-757-223): 23 aircraft (airframe model) - [Boeing 757-236](https://openairdocs.org/model/boeing-757-236): 20 aircraft (airframe model) - [Boeing 757-251](https://openairdocs.org/model/boeing-757-251): 18 aircraft (airframe model) - [Boeing 757-351](https://openairdocs.org/model/boeing-757-351): 16 aircraft (airframe model) - [Boeing 757-231](https://openairdocs.org/model/boeing-757-231): 13 aircraft (airframe model) - [Boeing 757-324](https://openairdocs.org/model/boeing-757-324): 9 aircraft (airframe model) - [Boeing 757-200 SERIES](https://openairdocs.org/model/boeing-757-200-series): 7 aircraft (airframe model) - [Boeing 757-204](https://openairdocs.org/model/boeing-757-204): 6 aircraft (airframe model) - [Boeing 757-225](https://openairdocs.org/model/boeing-757-225): 5 aircraft (airframe model) - [Boeing 757-230](https://openairdocs.org/model/boeing-757-230): 4 aircraft (airframe model) - [Boeing 757-258](https://openairdocs.org/model/boeing-757-258): 3 aircraft (airframe model) - [Boeing 757-256](https://openairdocs.org/model/boeing-757-256): 3 aircraft (airframe model) - [Boeing 757-260PF](https://openairdocs.org/model/boeing-757-260pf): 2 aircraft (airframe model) All 16 models: https://openairdocs.org/ad/2020-01-18/models.md Every aircraft: https://openairdocs.org/ad/2020-01-18/aircraft.md ## Related documents - [AD 2006-11-11](https://openairdocs.org/ad/2006-11-11) (historical): Fatigue cracking of PSEs · Boeing 757-200 Series, 757-200CB Series, 757-200PF Series and 1 more.
