Pursuant to subsection 5.9(2) of the Aeronautics Act, and after taking into account that the exemption is in the public interest and is not likely to affect aviation safety, I hereby exempt Canadian air operators that do not have an authorization to carry an external load with passengers on board from the requirements of section 703.25 of the Canadian Aviation Regulations (CARs), subject to the following conditions.
Section 703.25 stipulates "except where carriage of an external load has been authorized in a type certificate or supplemental type certificate, no air operator shall operate an aircraft to carry an external load with passengers on board."
The purpose of this exemption is to allow Canadian air operators to carry external loads on their float equipped aeroplanes while having passengers on board without an authorization in the type certificate or in a supplemental type certificate.
This exemption applies to Canadian air operators operating float equipped aeroplanes pursuant to Subpart 703 of the CARs and who are not authorized in a type certificate or supplemental type certificate to carry an external load with passengers on board.
This exemption does not apply to Canadian air operators who have been authorized in a type certificate or supplemental type certificate to carry an external load with passengers on board. These air operators shall comply with the conditions of the type certificate or supplemental type certificate.
This exemption is subject to the following conditions:
- The air operator shall conduct the operation in accordance with the procedures set out in Annex A as attached;
- The air operator shall conduct the operation in DAY/VFR conditions only;
- The air operator shall include and emphasize any special egress procedures in the passenger pre-flight briefing and the alternate escape routes shall be clearly marked;
- The Company Operations Manual shall contain direction to flight crews
concerning operations with external loads, including:
- a detailed description of the proposed means, which is readily repeatable, of locating and securing each load to the aircraft;
- the limitations and procedures associated with the carriage of external loads; and
- the requirements as set out in Annex A of this exemption.
- The air operator shall retain the results of the proving flight set out in Annex A for a period of not less than three years; and
- The Chief Pilot shall certify that every pilot authorized to carry external loads has been briefed and trained in accordance with section 723.88 of the Commercial Air Services Standard (CASS), and a record of this training shall be retained in the pilotâ€™s training file, in accordance with subsections 703.99(1) and (2) of the CARs.
This exemption is in effect until the earliest of the following:
- 23:59 EST on December 31, 2004;
- the date on which an amendment to the appropriate provision of the CARs or related standards comes into effect;
- the date on which any of the conditions set out in this exemption is breached;
- the date on which this exemption is cancelled in writing by the Minister where he is of the opinion that it is no longer in the public interest or that it is likely to affect aviation safety.
Datedat Ottawa, Canada this 2nd day of February 2004, on behalf of the Minister of Transport.

PROCEDURES AND RECOMMENDED PRACTICES FORCARRYING EXTERNAL LOADS
1. Load Location and Securing
- Loads shall be located so as not to impede emergency egress from the aircraft, and the airflow in the vicinity of pitot and static sources and other air scoops or exhaust ports shall not be adversely affected.
- Loads shall be located and attached to the aircraft in a manner that is both secure and repeatable, using a minimum of three separate ropes, straps or other means such that failure of any single connection does not create a hazard.
- Boats shall be mounted with the bow facing aft to minimize the effect of the turbulent wake on the tail surfaces, far enough aft of the propeller to prevent interference with the airflow and possible cavitation, and in a manner that prevents amounts of water from being caught and retained during take-off and landing that would create a safety hazard.
- Where a number of separate pieces are carried together (i.e., lumber, pipes), these pieces shall be fastened together to prevent a single piece from coming loose.
- The aircraft structure shall be protected from chafing, dents or damage caused by vibration or shifting of the external load.
- The pilot shall check the aircraft at the attachment points and general area of the external load for damage after each landing.
Note: Water collection and retention shall be assessed following a high-speed water taxi.
2. Proving Flight
For each particular type of load not previously carried by the air operator on a particular make and model of aeroplane operated by the air operator, the air operator shall conduct a proving flight that meets the following requirements:
- The air operator shall show that the flight characteristics are safe with the load attached and that the aircraft is safely controllable and manoeuvrable within the reduced operating envelope described under Operating Limitations below, with no exceptional pilot alertness, skill, or strength required. All changes to the aircraft weight and centre of gravity when passengers and internal cargo are carried shall be considered.
- The air operator shall maintain a record of the proving flight that
includes at least the following information:
- the date, time and location of the proving flight;
- the aircraft registration, type and model; and
- a description of the external load being tested.
Note: Proving flights are not necessary on subsequent flights carrying similar loads, provided that the loads are located and secured in an identical manner and the aircraft weight and centre of gravity are not significantly altered.
3. Operating Limitations
- The maximum gross take-off weight of the aircraft shall be reduced by twice the weight of any external load attached.
- The maximum bank angle during external load carriage shall not exceed 30 degrees.
- The maximum operating speed shall be no more than 90% of the maximum speed demonstrated to be safe during the proving flight and no less than 1.5 times the stalling speed.
