AD 2022-16-03 Airworthiness Directives; Continental Aerospace Technologies, Inc., Lycoming Engines, and Textron Lycoming/Subsidiary of Textron, Inc. Reciprocating Engines
Makes named: lycoming, continental. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to: (1) Continental Aerospace Technologies, Inc. reciprocating engine models identified in Table 1 to paragraph (c) of this AD that are equipped with an S-1200 series magneto having a serial number (S/N) between F21EA057 and F21KA009R, inclusive, manufactured and sold between May and November 2021; and (2) Lycoming Engines and Textron Lycoming/Subsidiary of Textron, Inc. reciprocating engine models identified in Table 2 to paragraph (c) of this AD that are equipped with an S-1200 series magneto authorized by Continental Aerospace Technologies, Inc. Parts Manufacturer Approval (PMA) Supplements 1-54, having an S/N between F21EA057 and F21KA009R, inclusive, manufactured and sold between May and November 2021. BILLING CODE 4910-13-P ER29JY22.664 ER29JY22.665 BILLING CODE 4910-13-C
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
For any affected magneto, within 25 operating hours time-in-service (TIS) or, if any affected magneto has accumulated more than 25 operating hours TIS, before further flight after the effective date of this AD: (1) Remove the affected magneto from the engine and replace with a part eligible for installation in accordance with the Corrective Action, paragraph III.A., of Continental Aerospace Technologies Critical Service Bulletin CSB673, Revision C, dated May 24, 2022 (the CSB); or (2) Remove the affected magneto from the engine and disassemble and inspect the affected magneto in accordance with the Corrective Action, paragraphs III.B.1. through III.B.8.a., of the CSB. (i) If, during the inspection required by paragraph (g)(2) of this AD, no white grease is detected, before further flight, inspect and replace the magneto components, as applicable, in accordance with the Corrective Action, paragraphs III.B.8.b.1 and III.B.8.b.2, of the CSB. Where the CSB specifies discarding the roller bearing, this AD instead requires removing the roller bearing from service. (ii) Reassemble and install the magneto in accordance with the Corrective Action, paragraph III.C., of the CSB.
Unsafe condition
This AD was prompted by a report of a manufacturing quality escape of improperly lubricated roller bearings installed in certain magnetos, which may result in overheating and magneto seizure. The FAA is issuing this AD to prevent failure of the magneto. The unsafe condition, if not addressed, could result in failure of one or more engines, in-flight shutdown, and loss 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.
