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 adversely affect aviation safety, I hereby exempt Canadian heliport operators, from the requirements of paragraph325.46(2)(a) of the Heliport Standards made pursuant to subsection 305.46(2) of the Canadian Aviation Regulations, subject to the following conditions.
Paragraph 325.46(2)(a) of the Heliport Standards stipulates that for the purposes of subsection 305.46(2) of the Canadian Aviation Regulations, the requirement in respect of fire protection for a rooftop heliport, is that the (a) main structural support beams that could be exposed to a fuel spill must have a fire-resistance rating of not less than 2 hours.
For the purposes of this exemption, landing pad edge means the outer edge of Final Approach and Take-off Area (FATO) when the FATO and the Touchdown and Lift-off Area (TLOF) are coincidental.
For the purposes of this exemption, Class A rating means a 2 hour fire resistance rating.
This exemption authorizes Canadian heliport operators to use an alternate means of meeting the intent of the 2 hour fire resistance rating for rooftop heliports, in accordance with the provisions of:
- the National Fire Protection Association publication NFPA 418 – Standards for Heliports – 2011 Edition; and
- Sections 218(b), Chapter 2, 317(b), Chapter 3 or 417(b), Chapter 4 of the U.S. Department of Transportation – Federal Aviation Administration –Advisory Circular AC150-5390-2C dated April 24, 2012, pending formal amendment of CAR 325 - Heliport Standards.
This exemption applies to all Canadian heliport operators.
The exemption must be subject to the following conditions:
- Where the landing pad is nonporous, fuel-tight, and provided with a proper drainage system, and fuel cannot flow to main structural support members, the main structural support members would not need to be fire rated, provided that;
- the rooftop landing pad surface is constructed of approved non-combustible, nonporous materials; and
- the contiguous building roof covering within 50 ft (15.2 m) of the landing pad edge has a Class A rating.
- A copy of this exemption must be inserted into the Heliport Operations Manual.
This exemption is in effect until the earliest of the following:
- On 15 March 2019 at 23:59 (EST);
- the date on which any of the condition set out in this exemption is breached;
- the date on which the exemption is cancelled by the Minister, in writing, where he is of the opinion that it is no longer in the public interest, or that it is likely to adversely affect aviation safety.
Dated at Ottawa, Ontario, Canada, this 17th day of March, 2015, on behalf of the Minister of Transport.
