(d) 

Index D. 

Three vehicles— 

(1) One vehicle carrying the extin-

guishing agents as specified in para-
graphs (a)(1) or (a)(2) of this section; 
and 

(2) Two vehicles carrying an amount 

of water and the commensurate quan-
tity of AFFF so the total quantity of 
water for foam production carried by 
all three vehicles is at least 4,000 gal-
lons. 

(e) 

Index E. 

Three vehicles— 

(1) One vehicle carrying the extin-

guishing agents as specified in para-
graphs (a)(1) or (a)(2) of this section; 
and 

(2) Two vehicles carrying an amount 

of water and the commensurate quan-
tity of AFFF so the total quantity of 
water for foam production carried by 
all three vehicles is at least 6,000 gal-
lons. 

(f) 

Foam discharge capacity. 

Each air-

craft rescue and firefighting vehicle 
used to comply with Index B, C, D, or 
E requirements with a capacity of at 
least 500 gallons of water for foam pro-
duction must be equipped with a tur-
ret. Vehicle turret discharge capacity 
must be as follows: 

(1) Each vehicle with a minimum- 

rated vehicle water tank capacity of at 
least 500 gallons, but less than 2,000 
gallons, must have a turret discharge 
rate of at least 500 gallons per minute, 
but not more than 1,000 gallons per 
minute. 

(2) Each vehicle with a minimum- 

rated vehicle water tank capacity of at 
least 2,000 gallons must have a turret 
discharge rate of at least 600 gallons 
per minute, but not more than 1,200 
gallons per minute. 

(g) 

Agent discharge capacity. 

Each air-

craft rescue and firefighting vehicle 
that is required to carry dry chemical, 
halon 1211, or clean agent for compli-
ance with the Index requirements of 
this section must meet one of the fol-
lowing minimum discharge rates for 
the equipment installed: 

(1) Dry chemical, halon 1211, or clean 

agent through a hand line—5 pounds 
per second. 

(2) Dry chemical, halon 1211, or clean 

agent through a turret—16 pounds per 
second. 

(h) 

Extinguishing agent substitutions. 

Other extinguishing agent substi-

tutions authorized by the Adminis-
trator may be made in amounts that 
provide equivalent firefighting capa-
bility. 

(i) 

AFFF quantity requirements. 

In ad-

dition to the quantity of water re-
quired, each vehicle required to carry 
AFFF must carry AFFF in an appro-
priate amount to mix with twice the 
water required to be carried by the ve-
hicle. 

(j) 

Methods and procedures. 

FAA Advi-

sory Circulars contain methods and 
procedures for ARFF equipment and 
extinguishing agents that are accept-
able to the Administrator. 

(k) 

Implementation. 

Each holder of a 

Class II, III, or IV Airport Operating 
Certificate must implement the re-
quirements of this section no later 
than 36 consecutive calendar months 
after June 9, 2004. 

[Doc. No. FAA–2000–7479, 69 FR 6424, Feb. 10,

§ 139.319

Aircraft rescue and fire-

fighting: Operational requirements. 

(a) 

Rescue and firefighting capability. 

Except as provided in paragraph (c) of 
this section, each certificate holder 
must provide on the airport, during air 
carrier operations at the airport, at 
least the rescue and firefighting capa-
bility specified for the Index required 
by § 139.317 in a manner authorized by 
the Administrator. 

(b) 

Increase in Index. 

Except as pro-

vided in paragraph (c) of this section, if 
an increase in the average daily depar-
tures or the length of air carrier air-
craft results in an increase in the Index 
required by paragraph (a) of this sec-
tion, the certificate holder must com-
ply with the increased requirements. 

(c) 

Reduction in rescue and firefighting. 

During air carrier operations with only 
aircraft shorter than the Index aircraft 
group required by paragraph (a) of this 
section, the certificate holder may re-
duce the rescue and firefighting to a 
lower level corresponding to the Index 
group of the longest air carrier aircraft 
being operated. 

(d) 

Procedures for reduction in capa-

bility. 

Any reduction in the rescue and 

firefighting capability from the Index 
required by paragraph (a) of this sec-
tion, in accordance with paragraph (c)
