AD 2019-06-13 Airworthiness Directives; The Boeing Company Airplanes
Models named: 787 series. 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 series airplanes, certificated in any category.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Except as required by paragraphs (i) and (k) of this AD: For airplanes with an original certificate of airworthiness or original export certificate of airworthiness issued on or before the effective date of this AD, at the applicable times specified in paragraph 5, “Compliance,” of Boeing Alert Service Bulletin B787-81205-SB270037-00, Issue 003, dated December 3, 2018, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB270037-00, Issue 003, dated December 3, 2018.
Unsafe condition
This AD was prompted by reports of hydraulic leakage caused by damage to aileron and elevator actuators from lightning strikes. We are issuing this AD to address hydraulic leakage in aileron and elevator power control units (PCUs), which, when coupled with an independent subsequent loss of two hydraulic systems, could result in an inability to maintain aileron or elevator actuator stiffness and lead to airplane control surface oscillations, which could damage the control surfaces and cause reduced controllability of the airplane.
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.
