JAR 29.1001 Fuel jettisoning
If a fuel jettisoning system is installed, the
following apply:
(a) Fuel jettisoning must be safe during all
flight regimes for which jettisoning is to be
authorised.
(b) In showing compliance with subparagraph
(a) of this paragraph, it must be shown
that –
(1) The fuel jettisoning system and its
operation are free from fire hazard;
(2) No hazard results from fuel or fuel
vapours which impinge on any part of the
rotorcraft during fuel jettisoning; and
(3) Controllability of the rotorcraft
remains satisfactory throughout the fuel
jettisoning operation.
(c) Means must be provided to automatically
prevent jettisoning fuel below the level required
for an all-engine climb at maximum continuous
power from sea-level to 5000 ft altitude and
cruise thereafter for 30 minutes at maximum range
engine power.
(d) The controls for any fuel jettisoning
system must be designed to allow flight personnel
(minimum crew) to safely interrupt fuel
jettisoning during any part of the jettisoning
operation.
(e) The fuel jettisoning system must be
designed to comply with the powerplant
installation requirements of JAR 29.901 (c).
(f) An auxiliary fuel jettisoning system
which meets the requirements of sub-paragraphs
(a), (b), (d) and (e) of this paragraph may be
installed to jettison additional fuel provided it has
separate and independent controls.
