Plain English Summary

4/10 complexity

This directive requires inspection of bladder-type fuel cells on listed Cessna 207 aeroplanes and a log‑book entry recording the result. If fuel cells show wrinkles or folds, maintenance must purge the fuel system of moisture or contaminants; additional purging may be required at each Maintenance Release for affected cells. Compliance timing differs depending on whether the aircraft was modified under Cessna SIL SE 84-9 Rev 1. It affects aircraft owners, operators and maintenance personnel responsible for airworthiness and record-keeping.

Applicability: All models with S/Nos as listed in Cessna SIL SE 84-4.

Requirement: Inspect fuel cells in accordance with Cessna SIL SE 84-4 and record the result in the aircraft log book. Where cells exhibit wrinkles or folds, purge fuel system of moisture or other contaminants.

Rev 1.

Initially, before further flight after 31 August 1984 for cells currently fitted, and at installation of any cell after 31 August 1984. Thereafter, for cells that exhibited signs of unacceptable wrinkles or folds at initial inspection, repeat the system purging procedures at each issue of a new Maintenance Release.

2. AIRCRAFT MODIFIED IN ACCORDANCE WITH CESSNA SIL SE 84-9, Rev 1.

When future cell replacement is required, carry out further SIL SE 84-9 Rev 1.

Background: This Directive promulgates the latest revision to Cessna SIL SE 84-9 containing “Helpful Hints” useful to maintenance personnel. The fuel cap testing requirement has been removed and now becomes the subject of a separate Directive. Editorial changes and a requirement for log book statements are also included.
