AD 2015-19-09 Airworthiness Directives; The Boeing Company Airplanes
Models named: 787-8. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to all The Boeing Company Model 787-8 airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 30 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, to add Airworthiness Limitation (AWL) Number 28-AWL-ACT, “Engine and APU Fuel Shutoff Valve (Fuel Spar Valve) Actuator Test,” by incorporating the information specified in figure 1 to paragraph (g) of this AD into the Airworthiness Limitations Section of the Instructions for Continued Airworthiness. This may be accomplished by inserting a copy of Airworthiness Limitation Number 28-AWL-ACT, “Engine and APU Fuel Shutoff Valve (Fuel Spar Valve) Actuator Test,” into the maintenance or inspection program, as applicable. For the airplanes identified in the applicability note of Airworthiness Limitation Number 28-AWL-ACT, “Engine and APU Fuel Shutoff Valve (Fuel Spar Valve) Actuator Test,” the initial compliance time for accomplishing the actions specified in figure 1 to paragraph (g) of this AD is within 10 days after accomplishment of the maintenance or inspection program revision, as applicable, required by this paragraph. When the engine and APU fuel shutoff valve actuators have been replaced as required by paragraph (i) of this AD, the Airworthiness Limitation Number 28-AWL-ACT, “Engine and APU Fuel Shutoff Valve (Fuel Spar Valve) Actuator Test,” required by this paragraph may be removed from the maintenance or inspection program, as applicable. Figure 1 to Paragraph ( g ) of This AD: Engine and APU Fuel Shutoff Valve (Fuel Spar Valve) Actuator Test AWL No. Task Interval Applicability Description 28-AWL-ACT ALI 10 DAYS ALL Engine and APU Fuel Shutoff Valve (Fuel Spar Valve) Actuator Test INTERVAL NOTE: Not required on days when the airplane is not operated. The test must be done before further flight if it has been 10 or more calendar days since the last inspection APPLICABILITY NOTE: This AWL applies to airplanes with Eaton Aerospace Ltd. fuel spar valve actuators having part number 53-0037 installed at the engine or APU fuel shutoff valve location Concern: The fuel spar valve actuator design can result in airplanes operating with a failed fuel spar valve actuator that is not reported. A latently failed fuel spar valve actuator would prevent fuel shutoff to an engine or APU. In the event of certain engine or APU fires, the potential exists for an engine or APU fire to be uncontrollable. Perform the following tests in accordance with Boeing Service Bulletin B787-81205-SB280015-00, Issue 002, dated June 19, 2014. 1. Do PART 1: ENGINE FUEL SPAR VALVE ACTUATOR TEST as described in Boeing Service Bulletin B787-81205-SB280015-00, Issue 002, dated June 19, 2014. a. If the left engine fuel spar valve actuator has part number 53-0037, perform the left engine fuel spar valve actuator test. b. If the right engine fuel spar valve actuator has part number 53-0037, perform the right engine fuel spar valve actuator test. c. If either test fails, repair faults as required (refer to Boeing Airplane Maintenance Manual 28-22-02). 2. Do PART 2: APU FUEL SPAR VALVE ACTUATOR TEST as described in Boeing Service Bulletin B787-81205-SB280015-00, Issue 002, dated June 19, 2014. a. If the APU fuel spar valve actuator has part number 53-0037, perform the APU fuel spar valve actuator test. b. If the test fails, before further flight requiring APU availability, repair faults as required (refer to Boeing Airplane Maintenance Manual 28-25-03). NOTE: Dispatch may be permitted per MMEL 28-25-03 if the APU is not required for flight.
Unsafe condition
This AD was prompted by reports of a potential latent failure of the fuel shutoff valve actuator circuitry, which was not identified during actuator development. We are issuing this AD to detect and correct latent failures of the fuel shutoff valve to the engine and auxiliary power unit (APU), which could result in the inability to shut off fuel to the engine and APU and, in case of certain fires, an uncontrollable fire that could lead to structural failure.
Affected ADs
None.

You just looked this one up by hand
TrackAD holds all 12,278 of them and matches them against the aircraft you actually look after — airframe, engine, propeller and appliances in one pass — then works out what falls due and when.
- Bring your existing list in from a spreadsheet Paste the rows straight out of Excel. Headers like C/W Date and N/A are read for you.
- A copy that works when this does not One file. No internet, no login, no this software running. For the morning something has to be produced and the computer is not cooperating.
- $5 a month, or $50 a year Up to 50 aircraft on either.
