Two items need action. First: AD 2023-15-07 on the Continental IO-520-BA is [1]14 days overdue[1] — camshaft lot inspection, one-time. Last evaluated [1]2026-04-06 at 4 801.0 h[1]. Second: AD 2026-08-14 — oil cooler hose inspection — is due in [2]44 days[2] or at 4 901.0 h, whichever comes first. Recurring 100 h. [2]Parser flagged low confidence on the recurring-interval phrasing[2] — verify 100 h vs. 200 h before signing. Two compliance events cite the airframe in the last six months; neither supersedes the active findings.
“One-time inspection and replacement of discrepant camshaft lot numbers on Continental IO-520/IO-550. Applies to engine S/N 285441-R, lot 2007-Q3.”
“Oil cooler hose inspection — fire risk. Applies to IO-520-BA. Every 100 h recurring.”
Good. Now draft a 337 for the G5 install I did last week — use my note from 4-15.
Here's a draft. I pulled the STC and weight-and-balance numbers from your installation note on 2026-04-15 and cross-referenced the Garmin G5 AML. Review and sign when it reads correct.
