Applies to Model 737 series airplanes, line numbers 001 through 1425, equipped with non-modular aft lavatories, certificated in any category. Compliance required as indicated, unless previously accomplished. NOTE: "Non-modular" refers to lavatories which are not stand-alone components, and are assembled on the airplane. To prevent accumulation of combustible materials behind the airplane sidewall, accomplish the following: A. Within 3 months after the effective date of this AD, inspect the area behind the towel and cup dispenser for the presence of a shroud enclosing the dispenser back. 1. If the dispenser is equipped with a shroud which prevents material from falling behind the lavatory sidewall and is acceptable to the Manager, Seattle Aircraft Certification Office, or an FAA Principal Maintenance Inspector, no further action is required. 2. If an acceptable existing shroud has not been installed, inspect the area behind the towel and cup dispenser in the aft lavatories and remove all foreign material. Repeat this inspection at intervals not to exceed 3 months, until the requirements of paragraph B., below, are accomplished. B. Within 15 months after the effective date of this amendment, install a shroud behind the towel and cup dispenser in the aft lavatories, which encloses the dispenser back and prevents material from falling behind the sidewall, in a manner approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region, or an FAA Principal Maintenance Inspector. C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region. NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who may add any comments and then send it to the Manager, Seattle Aircraft Certification Office. D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD. This amendment, 39-5966, becomes effective August 11, 1988. ## Affected data sheets (1) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS A16WE](https://openairdocs.org/tcds/A16WE): The Boeing Company; names 9 of 17 models: 737-500 Series, 737-100 Series, 737-200C Series, 737-800 Series, 737-300 Series, 737-200 Series, 737-700 Series, 737-400 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: 823 (823 by airframe model, 0 by engine model) - Makers: Boeing 823 Models with the most aircraft: - [Boeing 737-823](https://openairdocs.org/model/boeing-737-823): 278 aircraft (airframe model) - [Boeing 737-800](https://openairdocs.org/model/boeing-737-800): 139 aircraft (airframe model) - [Boeing 737-824](https://openairdocs.org/model/boeing-737-824): 135 aircraft (airframe model) - [Boeing 737-832](https://openairdocs.org/model/boeing-737-832): 73 aircraft (airframe model) - [Boeing 737-890](https://openairdocs.org/model/boeing-737-890): 60 aircraft (airframe model) - [Boeing 737-724](https://openairdocs.org/model/boeing-737-724): 36 aircraft (airframe model) - [Boeing 737-790](https://openairdocs.org/model/boeing-737-790): 14 aircraft (airframe model) - [Boeing 737-752](https://openairdocs.org/model/boeing-737-752): 13 aircraft (airframe model) - [Boeing 737-400](https://openairdocs.org/model/boeing-737-400): 8 aircraft (airframe model) - [Boeing 737-852](https://openairdocs.org/model/boeing-737-852): 7 aircraft (airframe model) - [Boeing 737-500](https://openairdocs.org/model/boeing-737-500): 6 aircraft (airframe model) - [Boeing 737-436](https://openairdocs.org/model/boeing-737-436): 6 aircraft (airframe model) - [Boeing 737-700](https://openairdocs.org/model/boeing-737-700): 5 aircraft (airframe model) - [Boeing 737-300](https://openairdocs.org/model/boeing-737-300): 4 aircraft (airframe model) - [Boeing 737-883](https://openairdocs.org/model/boeing-737-883): 4 aircraft (airframe model) - [Boeing 737-205](https://openairdocs.org/model/boeing-737-205): 3 aircraft (airframe model) - [Boeing 737-490](https://openairdocs.org/model/boeing-737-490): 3 aircraft (airframe model) - [Boeing 737-484](https://openairdocs.org/model/boeing-737-484): 3 aircraft (airframe model) - [Boeing 737-732](https://openairdocs.org/model/boeing-737-732): 3 aircraft (airframe model) - [Boeing 737-524](https://openairdocs.org/model/boeing-737-524): 3 aircraft (airframe model) All 40 models: https://openairdocs.org/ad/88-14-07/models.md Every aircraft: https://openairdocs.org/ad/88-14-07/aircraft.md Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
