SPECIAL AIRWORTHINESS
INFORMATION BULLETIN
SAIB: CE-10-04
SUBJ: Smoke Detection: Cockpit Smoke and Fumes Date: October 8, 2009
This is information only. Recommendations aren’t mandatory.
Introduction:
This Special Airworthiness Information Bulletin is being issued to alert owners, operators, and
original equipment manufacturers (OEM) to an airworthiness concern regarding emergency checklist
procedures that apply to ventilating smoke and fumes from the airplane cockpit in general aviation
(GA) aircraft. Prior to 14 CFR § 23.831, Amendment 23-34, it was not required to include this into
the checklists regarding removing smoke and fumes from the airplane cockpit.
The airworthiness concern is not an unsafe condition that would warrant airworthiness directive (AD)
action under Title 14 of the Code of Federal Regulations (14 CFR) Part 39.
Background:
After an in-flight electrical fire in a Canadian-registered Cessna Model152 airplane, the
Transportation Safety Board of Canada recommended that the “FAA take action to review checklist
procedures dealing with smoke and fire in GA aircraft,” and include additional steps to eliminate
smoke or fumes. Emergency checklist procedures, for aircraft that were type certificated to CAR 3,
and those aircraft type certificated aircraft prior to 14 CFR Amendment 23-34, the Original
Equipment Manufacture (OEM) Pilot Operating Handbook (POH) did not address ventilating smoke
and fumes from the airplane cockpit.
The current 14 CFR part 23 (23-58 amendment) requires OEMs to include instructions in their pilot
operating handbook (POH) or airplane flight manual (AFM) to remove smoke from the cockpit and
passenger cabin of both pressurized and un-pressurized aircraft.
14 CFR FAR 23.831 (a) “Each passenger and crew compartment must be suitably
ventilated…”
14 CFR 23.831 (b) “If accumulation of hazardous quantities of smoke in the cockpit area is
reasonably probable, smoke evacuation must be readily accomplished starting with full
pressurization and without depressurizing beyond safe limits.”
14 CFR 23.1585 (a) “For all airplanes, information concerning normal, abnormal (if
applicable), and emergency procedures and other pertinent information necessary for safe
operation and the achievement of the scheduled performance must be furnished…”
Owners and operators may have modified their aircraft to meet operational requirements or
added/removed supplemental type certificates (STC). These alterations could require changes to the
original POH or AFM and associated emergency checklist or abnormal procedures checklist.
2
Recommendation:
There are no regulatory requirements in CAR 3 or prior to Amendment 23-24 and 23-42 of 14 CFR
part 23 requiring instructions in the POH or AFM to remove smoke or fumes from the cockpit and
passenger cabin. For airplanes where the OEM no longer exist, owners and operators may want to
contact the Experimental Aircraft Association (EAA) or airplane type clubs for information as to the
removal of smoke and fumes in their make and model airplane. These emergency checklists may
include the following statement: “to remove smoke or fumes from the cockpit do the following …” if
such a similar statement does not already exist in their POH or AFM.
The FAA recommends the following:
• owners and operators check their added/removed STC instructions for continued
airworthiness for the removal of smoke and fumes against the OEM issued Emergency
Checklist.
• If the OEM Emergency Checklist has no instructions for the removal of smoke or fumes in
the cockpit, then owners and operators contact the OEM of the make and model airplane for
emergency checklist instruction or additions.
• OEMs add to the emergency checklist steps for ventilating smoke and fumes from the cockpit
for their specific make and model. OEMs may have to issue service bulletins instructing
owners and operators where and what to write into the emergency checklist or issue a new
emergency checklist that contains instructions for the removal of smoke and fumes from the
cockpit.
