Cessna 150 and 152 Propellers: Exact Applications and Inspection Research

A propeller application is more specific than a manufacturer name or a general engine pairing. The full designation, aircraft model, year or configuration, dimensional limits and source notes belong together. These details explain why two apparently similar propellers cannot be treated as interchangeable from a short description.

Follow the supported application

The 1A102/OCM6948 reference covers recorded 150L/M and Reims applications. The 1A103/TCM6958 reference covers the 152 context. The 1A135/BRM7150 reference preserves the O-240-powered FRA150 applications.

Limits are part of eligibility

Read diameter and static-rpm fields with their model and configuration qualifiers. They are not a do-it-yourself repair or alteration procedure. Establish the installed identification and use the applicable controlled information when a mechanic assesses a discrepancy or proposed replacement.

Directive research follows the component

The TCM hub-crack directive reference illustrates installed-component applicability. An aircraft's ability to accept a propeller does not prove that the affected component is fitted, and a matching installation does not prove compliance.

Broader family evidence

Use the 150 propeller tables and 152 propeller tables for the broader application lists. Match the complete propeller designation, aircraft model and installation conditions before comparing diameter, pitch or static-RPM figures.

For a purchase, connect propeller identity with maintenance, repair and alteration records through the logbook guide. Historical application evidence does not establish today's parts availability, support arrangements or price. Keep those current-market questions separate from the technical eligibility reference.

Read the Full Propeller Designation

Several early and intermediate propeller applications appear in the family tables. Read the complete designation with its model-year range, engine and installation conditions. Similar manufacturer names or adjacent model years do not establish interchangeability. When comparing a proposed replacement, retain the suffixes and any approval reference and ask how the proposal matches the aircraft’s installed equipment and modification history. An application list is a starting point for that enquiry, not a purchase recommendation for an unidentified aircraft.

The remaining installation references include Sensenich 69CK designations and a consolidated McCauley GCM/HCM/PCM comparison. The latter keeps the differing U.S. and Reims year ranges visible together.

Find service information by its publication number

McCauley now directs publication users to 1View and its service information portal. A legacy application-guide link can help identify a research question without establishing that the owner has the relevant maintenance publication. Keep those uses separate.

The propeller-records guide connects the installed serial, work history and aircraft installation. It is particularly useful when a logbook contains references to several propellers. Start with the unit actually fitted, then use this hub's designation-specific references to select the appropriate application and AD research.

Read static limits in their installation context

The static-RPM interpretation guide explains how to read that field beside the exact engine, propeller and aircraft application. It does not provide a run-up procedure or replace the controlled instructions needed to assess a discrepancy.

Use replacement-part applicability when comparing a proposed propeller with the installed unit. Preserve suffixes, configuration notes and approval references rather than reducing the enquiry to a manufacturer name and a pair of RPM numbers.
