What aircraft is 69-78533-2 used on?

The Boeing 737. Because the '-2' dash applies to specific effectivity, confirm the variant (737 Classic 300/400/500 vs 737 NG 600/700/800/900) and configuration against the IPC before treating another dash as equivalent.

What condition codes are available for 69-78533-2?

As an avionics rotable it is offered Overhauled (OH), Serviceable (SV), or As-Removed (AR); New (NE) is generally OEM-only. OH/SV units should include a functional-test record against the applicable CMM.

What certification documents ship with 69-78533-2?

FAA 8130-3 / EASA Form 1, dual release preferred. An airworthiness release is expected for an installed avionics LRU; a Certificate of Conformance alone is not normally sufficient.

Are there interchangeable part numbers for 69-78533-2?

No DLA FLIS / NSN cross-reference was identified. Interchangeability among dash numbers is governed by the Boeing IPC — verify the '-2' configuration against the IPC and the aircraft's mod/SB status before substituting another dash.

Can an ice-detection fault keep a 737 on the ground?

Depending on configuration and route, an ice-detection logic fault can drive Minimum Equipment List (MEL) restrictions on icing operations, so it can be dispatch-relevant. Confirm MEL relief for the specific configuration and keep a serviceable spare for AOG (Aircraft on Ground) resilience.

69-78533-2 - Boeing 737 Module Assy - Ice Detection System Logic for Boeing 737

69-78533-2 is an Ice Detection System logic module assembly for the Boeing 737, supplied by BAE Systems Controls, Inc. The module is the processing/logic Line Replaceable Unit (LRU) of the airframe ice-detection system: it interprets the signal from the aircraft's ice-detector probe(s) and provides ice-presence logic and indication used to alert the flight crew to icing conditions and, depending on configuration, to support anti-ice system management (ATA 30 — Ice and Rain Protection).

The '69-' prefix denotes a Boeing part number and the '-2' dash a specific configuration/revision; the applicable variant effectivity (737 Classic 300/400/500 versus 737 NG 600/700/800/900) should be confirmed against the 737 IPC. The unit is an avionics rotable installed in an electronics bay and is subject to functional test on installation. Mod and service-bulletin status should be checked so that the unit's configuration matches the receiving aircraft.

Avionics LRUs of this type are typically sourced overhauled (OH) or serviceable (SV) with FAA 8130-3 / EASA Form 1 and are testable on the bench against the applicable CMM; new units are available through Boeing distribution. Confirm the dash-number effectivity for the specific 737 variant before procurement.
