AD 97-01-13: Cessna S51-10 Replacement-Hose Research

FAA AD 97-01-13 is a useful example of a component concern that cannot be screened out by the age of a Cessna 150 or 152. Its aircraft list is broad, while the required investigation follows a particular replacement hose and historical installation window. The buyer's question is what was installed and what the records establish, not whether the aircraft left the factory in the 1990s.

Aircraft scope and component scope differ

The FAA directive text lists all serials of its named 150, A150, 152 and Reims variants. Paragraph (a) requires a records check for Cessna S51-10 fuel, oil or hydraulic hoses replaced between March 1995 and 3 February 1997. The historical initial deadline was 60 hours time in service or 60 calendar days, whichever occurred first; it is not a fresh allowance starting at a later purchase.

Keep the exact model list with the review. A broad family label does not justify adding an unlisted variant, and a listed airframe does not establish that the suspect hose was installed. Replacement history supplies the next part of the inquiry.

What the follow-up check concerns

Paragraphs (b) and (c) address diagonal or spiral external reinforcement wrap and replacement with the specified criss-cross-wrap hose. For the listed 150/152 variants, the directive references SEB96-15 dated 18 October 1996. Paragraph (d) separately prohibits installing the specified suspect hose. Consult the applicable SEB96-15 instructions for the complete service procedure, together with the directive.

This is a defined hose issue, not evidence that all old fuel hoses share the same defect. Keep ordinary hose condition and maintenance planning in the broader fuel-system inquiry. A finding about age or wear should not be relabeled as this directive's particular manufacturing concern without the component evidence.

Use the allowed records check accurately

The directive expressly permits its paragraph (a) and (b) checks by an owner/operator holding at least a private pilot certificate, with the stated record entry. That provision does not extend to every replacement action or every other AD. Read its scope before applying a general assumption about owner preventive maintenance.

For a historical file, locate the original review entry and identify the records it used. If the replacement period is missing from the logbooks, preserve that gap as a question for the maintenance reviewer. An empty page in the surviving file cannot prove no replacement occurred.

Record the conclusion and its basis

A useful research note identifies the directive, aircraft model, component question, supporting record locator and any unresolved evidence. If a later hose replacement is documented, retain the installed part information rather than merely adding another “AD done” statement.

Continue to the AD status-record guide for the file structure and the logbook guide for gaps in the chronology. This page explains the historical requirement and component trail; it does not establish current supersedure status, an approved alternative method or compliance of an individual aircraft.
