Section 31.82 Instructions for Continued Airworthiness.
The applicant must prepare Instructions for Continued Airworthiness in
accordance with appendix A to this
part that are acceptable to the Administrator. The instructions may be incomplete at type certification if a program exists to ensure their completion
prior to delivery of the first balloon or
issuance of a standard certificate of
airworthiness, whichever occurs later.

Section 31.83

Conspicuity.

The exterior surface of the envelope
must be of a contrasting color or colors
so that it will be conspicuous during
operation. However, multicolored banners or streamers are acceptable if it
can be shown that they are large
enough, and there are enough of them
of contrasting color, to make the balloon conspicuous during flight.
Section 31.85

Required basic equipment.

In addition to any equipment required by this subchapter for a specific
kind of operation, the following equipment is required:
(a) For all balloons:
(1) [Reserved]
(2) An altimeter.
(3) A rate of climb indicator.
(b) For hot air balloons:
(1) A fuel quantity gauge. If fuel cells
are used, means must be incorporated
to indicate to the crew the quantity of
fuel in each cell during flight. The
means must be calibrated in appropriate units or in percent of fuel cell
capacity.
(2) An envelope temperature indicator.
(c) For captive gas balloons, a compass.

A31.1

GENERAL

(a) This appendix specifies requirements
for the preparation of Instructions for Continued Airworthiness as required by Section 31.82.
(b) The Instructions for Continued Airworthiness for each balloon must include the
Instructions for Continued Airworthiness for

and any required information relating to the
interface of those parts with the balloon. If
Instructions for Continued Airworthiness are
not supplied by the part manufacturer for a
balloon part, the Instructions for Continued
Airworthiness for the balloon must include
the information essential to the continued
airworthiness of the balloon.
(c) The applicant must submit to the FAA
a program to show how changes to the Instructions for Continued Airworthiness made
