Effects of this Revision on airplanes on which the Original Issue was previously done:
None.
REASON FOR REVISION This revision is sent to add delivered 777 airplanes that had Ipeco powered Captain's and First Officer's seats installed during production or in retrofit, and all future deliveries with Ipeco powered Captain's and First Officer's seats to the effectivity of this service bulletin. This revision also adds instructions to identify specific Captain's and First Officer's seat serial numbers for seat part numbers 3A258-0041-01-1 and 3A258-0042-01-1. Also seat part numbers 3A258-0041-01-2 and 3A258-0042-01-2 were added to the Serviceable Seat definition.

Commercial Airplanes 777 Service Bulletin
SPECIAL ATTENTION SummaryNumber: 777-25-0607Original Issue: January 09, 2014 Revision 1: July 17, 2018 ATA System: 2511 SUBJECT: EQUIPMENT / FURNISHINGS - Flight Compartment Seats - Captain's and First Officer's Seat - Manual Override Cable Inspection and Adjustment BOEING RECOMMENDS THAT EACH OPERATOR EXAMINE THIS DOCUMENT IMMEDIATELY.
CONCURRENT REQUIREMENTS Refer to Paragraph 1.B., Concurrent Requirements.
BACKGROUND Accomplishment of this service bulletin will make sure that Captain's and First Officer's seats do not have un-commanded movement due to an improperly adjusted cable for the manual release lever. If this service bulletin is not done, the manual control lever cable could be incorrectly adjusted which could result in its clutch mechanism (dogs) not engaging correctly and cause an un-commanded seat movement. An un-commanded seat movement during a critical part of a flight, such as take-off or landing could cause a flight control obstruction or unintended flight control input which could result in the loss of the ability to control the airplane.
A 747 operator reported that during a takeoff, the First Officer's seat unlocked from it's seat tracks and moved aft. The first officer was unable to control the airplane and the captain took over the controls to avoid a rejected takeoff. The unlocking of the seat from the seat tracks was caused by actuator damage which was a result of incorrect adjustment of the seats manual release lever cable, allowing the clutch dogs to only partially engage.
Because 777 airplanes use the same seats in the flight compartment, Boeing has issued this service bulletin to do a one time inspection, and if necessary an adjustment, in accordance with an Ipeco Service Bulletin. Two Ipeco Service Bulletins have been issued to account for different part number seats installed. Because of in-service seat interchangeability, operators are told to inspect the part number of the seats installed and use the applicable Ipeco Service Bulletin.
This service bulletin gives instructions to find the identification of the installed Captain's and First Officer's seats and to do an inspection, and if necessary an adjustment, of each seat's fore/aft manual control lever and vertical manual control lever in accordance with an Ipeco Service Bulletin. The inspection, and if necessary the adjustment of the manual control levers of the Captain's and First Officer's seats, will make sure that the seats do not have un-commanded seat movement due to improperly adjusted fore/aft and vertical manual control levers.
Boeing Service Related Problem (SRP) 777-SRP-25-0320 is related to this service bulletin.
Boeing Fleet Team Digest (FTD) 777 FTD 25-13006 is related to this service bulletin.

Find the part number of the Captain's and First Officer's seat installed on the airplane. If specific seat part numbers are found find the serial number of those seats. For specific part numbers and serial numbers of Captain's and First Officer's seats do a Detailed Inspection of the fore/aft manual control lever and the vertical manual control lever on each seat for looseness in accordance with the applicable Ipeco Service Bulletin. If a control lever inspection is not within limits, remove the seat and install a serviceable seat. Do an operational test of each adjusted seat.
NOTE: A serviceable Captain's seat in this service bulletin is defined as seat part number 3A258-0041-01-2, or a Captain's seat that has done the inspections and all applicable corrective actions in accordance with the applicable Ipeco service bulletin. A serviceable First Officer's seat in this service bulletin is defined as seat part number 3A258-0042-01-2, or a First Officer's seat that has done the inspections and all applicable corrective actions in accordance with the applicable Ipeco service bulletin.
