AD 80-06-03: Cessna 150M and 152 Flap Cable Clamps
AD 80-06-03 concerns wing-flap cable clamps in specified Cessna 150M, A150M, 152 and A152 serial groups. The retained applicability explicitly includes A1500433 in the A152 context. This is a useful example of why a serial prefix alone cannot determine the aircraft identity or the correct applicability result.

The serial groups in the retained record
The local summary lists 150M serials 15078506-15079405, A150M serials A1500685-A1500734, 152 serials 15279406-15283354, and the A152 group described as A1500433 plus A1520735-A1520867. Preserve those groups separately. Joining them into one numeric span would cross different model identities and obscure the special aircraft record.

These are retained research records, not a live determination of regulatory status. The full directive and any relevant later action need to be checked before making a compliance decision. A model or serial match identifies a research obligation; it does not show that the affected installation remains present or that the required action has been performed.

Why A1500433 matters
The accepted serial evidence treats A1500433 as an A152 exception. Looking only at its A150 prefix could send a researcher toward the wrong model group. The Cessna 152 serial guide preserves that exception and should be used when the aircraft identity is in doubt.
The same principle applies to abbreviated serials in logs. Preserve the original notation, then compare it with the model and full identity context. Do not silently supply a prefix merely because the resulting number fits a nearby production range.
Cable clamps versus actuator work
The issue associated with this directive concerns the cable-clamp installation. It is separate from the jack screw, ball nut and stop arrangements discussed in the flap actuator guide. A replacement actuator entry does not automatically explain the cable clamps, and a cable-clamp action does not describe the condition of every other flap component.

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Cessna 150 | KI-021 | Flaps / Cables | Wing flap cable clamp configuration | Specified aircraft require an approved cable clamp/hardware configuration. | 150M 15078506-15079405; A150M A1500685-A1500734; 152 15279406-15283354; A152 A1500433/A1520735-0867. | SERIAL | HIGH | Cable movement/chafing or flap-system malfunction. | Confirm P/N 0560037-1 clamp/hardware installation and records. | Install specified clamp/hardware per AD. | FAA AD - mandatory | AD 80-06-03 | [1] | HIGH | HIGH | Exact serial parsing required. |

The flap systems page provides the architecture around those components. Use it to orient the research, then follow the applicable maintenance and directive references for the actual installation detail.

Reading a useful compliance entry
An informative record connects the exact aircraft identity, the directive reference, the work performed and the applicable instructions. A general note that “flaps checked” may describe legitimate maintenance, but it does not explain which directive or component was addressed. Preserve that distinction in a prebuy file. The goal is to identify the relevant evidence and any remaining uncertainty, rather than treating a successful flap movement or a source-table match as proof of documented compliance.
