Applies to all Model DC-8 Series Aircraft. Compliance required as indicated. There have been failures of the landing gear bogie beam due to cracking initiated by corrosion in an area where the bogie beam surface had been damaged. To preclude further failures of this type, accomplish the following on bogie beam assemblies, P/N's 5760635, 5760630, or 5716469: (a) Within 1000 hours' time in service after the effective date of this AD, as amended, for bogie beam assemblies having more than 1000 hours' time in service as of the effective date of this AD, as amended, and prior to the accumulation of 2000 hours' time in service for bogie beam assemblies having less than 1000 hours' time in service as of the effective date of this AD, as amended, and thereafter at intervals not to exceed 3000 hours' time in service, accomplish the inspection and rework outlined in (b). (b) Conduct a thorough visual inspection of the bogie beam to detect any evidence of nicks, scratches, or impact dents. Replace bogie beams exhibiting such defects before further flight, unless the part is reworked before further flight in accordance with the following as applicable: (1) Nicks, scratches, and impact dents up to 0.005 inch in depth must be blended smooth and repainted in accordance with (b)(4). (2) Nicks, scratches, and impact dents greater than 0.005 inch in depth but not exceeding 0.030 inch, shall be blended smooth and repainted in accordance with (b)(4). The reworked area shall be shot peened prior to an accumulation of 6,000 hours' time in service after the rework. Accomplish shot peening as indicated in (b)(5). (3) If bogie beam damage exceeds 0.030 inch in depth, any rework to remove such damage shall be accomplished in accordance with FAA approved Douglas rework procedures. Any other proposed rework shall be submitted by FAA Western Region, Attention: Chief, Engineering and Manufacturing Branch, for evaluation. (4) The rework referred to in (b)(1) and (b)(2) shall be accomplished in accordance with DC-8 Maintenance Manual Chapter 32-0, paragraphs (A), page 201 dated September 1, 1960, and (D), page 203 dated March 15, 1961, or FAA approved equivalent. (5) Shot peening referred to in (b)(2) shall be accomplished in accordance with DC-8 Overhaul Manual, Chapter 13-3-2, paragraph 3(L), page 13, dated November 1, 1963, or FAA approved equivalent. (c) Upon request of an operator, an FAA maintenance inspector, subject to prior approval of the Chief, Engineering and Manufacturing Branch, FAA Western Region, may adjust the repetitive inspection intervals specified in this AD to permit compliance at an established inspection period of the operator if the request contains substantiating data to justify the increase for such operator. NOTE: The cleaning methods specified in DC-8 Maintenance Manual Chapter 12-13-0, page 201, paragraph (1), dated August 1, 1960, should be used in cleaning the landing gear bogie beam. Amendment 692 was effective March 30, 1964. Amendment 727 was effective May 6, 1964. This Amendment 39-1905 becomes effective August 2, 1974. ## Affected data sheets (1) (OpenAirDocs) The type certificate data sheets whose models the AD names. - [TCDS 4A25](https://openairdocs.org/tcds/4A25): The Boeing Company; names 27 of 27 models: DC-8-41, DC-8-52, DC-8-61, DC-8-53, DC-8-51, DC-8-63, DC-8-11, DC-8-72F… ## 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: 8 (8 by airframe model, 0 by engine model) - Makers: Douglas 5, Mcdonnell Douglas 3 Models with the most aircraft: - [Douglas DC-8-73](https://openairdocs.org/model/douglas-dc-8-73): 2 aircraft (airframe model) - [Douglas DC-8-73F](https://openairdocs.org/model/douglas-dc-8-73f): 2 aircraft (airframe model) - [Mcdonnell Douglas DC-8-62](https://openairdocs.org/model/mcdonnell-douglas-dc-8-62): 1 aircraft (airframe model) - [Mcdonnell Douglas DC-8-63](https://openairdocs.org/model/mcdonnell-douglas-dc-8-63): 1 aircraft (airframe model) - [Mcdonnell Douglas DC-8-63F](https://openairdocs.org/model/mcdonnell-douglas-dc-8-63f): 1 aircraft (airframe model) - [Douglas DC-8-72](https://openairdocs.org/model/douglas-dc-8-72): 1 aircraft (airframe model) All 6 models: https://openairdocs.org/ad/64-05-02/models.md Every aircraft: https://openairdocs.org/ad/64-05-02/aircraft.md Its text cites no advisory circulars or STCs. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
