Cessna 150 and 152 Propeller Records: Identity, Work and Installation

Propeller records should connect the physical propeller to its work history and aircraft installation. For a Cessna 150 or 152, the airframe serial alone cannot identify a replacement propeller, establish its dimensions after repair, or show compliance with a component-specific directive. Preserve the full propeller designation and serial as separate identifiers.

Follow the component as well as the aircraft

The U.S. maintenance-record rule includes propellers in its record requirements. AC 43-9D explains that relevant component information must be retained even though separate individual logbooks are not universally required. A dedicated propeller book may make the history easier to follow, but the format is less important than whether the necessary information can be traced.

Compare the installed unit's identity with its shop paperwork and the aircraft installation entry. If a seller supplies records for an earlier propeller, keep them as history rather than attributing that work to the present unit. Ask the reviewer to resolve unclear serials or abbreviated designations before comparing service information.

Application lists and shop measurements answer different questions

The Sensenich installation list is explicitly a reference rather than a replacement for approval and service documents. A nominal designation in an application list is not a measurement of a repaired blade. Likewise, a propeller that appears in a list still needs the correct aircraft, engine and approval context.

Use the Sensenich 69CK guide when comparing its standard and spacer-related variants. For McCauley installations, start with the exact propeller reference rather than shortening every designation to the diameter and pitch numbers. The aim is to preserve enough identity to select the right evidence, not to interpret workshop limits from a name.

Find the publication that addresses the question

McCauley publication-access guidance now directs manual users to 1View and service-document users to its service information route. Record the publication number and revision actually consulted. A saved link to an old application guide does not prove access to the maintenance instructions needed for a current inspection or repair.

Prepare focused prebuy questions

Ask whether the supplied history belongs to the installed serial, which work the shop performed, what installation record connects it to this aircraft, and which applicable AD entries remain to be checked. The prebuy guide can incorporate those questions into an agreed scope. This record trail is especially useful when an aircraft has changed engines or propellers during a long ownership history.
