14 CFR Ch. I (1–1–19 Edition) 

§ 34.7 

§ 34.7

Exemptions. 

Notwithstanding part 11 of the Fed-

eral Aviation Regulations (14 CFR part 
11), all petitions for rulemaking involv-
ing either the substance of an emission 
standard or test procedure prescribed 
by the EPA that is incorporated in this 
FAR, or the compliance date for such 
standard or procedure, must be sub-
mitted to the EPA. Information copies 
of such petitions are invited by the 
FAA. Petitions for rulemaking or ex-
emption involving provisions of this 
FAR that do not affect the substance 
or the compliance date of an emission 
standard or test procedure that is pre-
scribed by the EPA, and petitions for 
exemptions under the provisions for 
which the EPA has specifically granted 
exemption authority to the Secretary 
of Transportation are subject to part 11 
of the Federal Aviation Regulations (14 
CFR part 11). Petitions for rulemaking 
or exemptions involving these FARs 
must be submitted to the FAA. 

(a) 

Exemptions based on flights for 

short durations at infrequent intervals. 

The emission standards of this part do 
not apply to engines which power air-
craft operated in the United States for 
short durations at infrequent intervals. 
Such operations are limited to: 

(1) Flights of an aircraft for the pur-

pose of export to a foreign country, in-
cluding any flights essential to dem-
onstrate the integrity of an aircraft 
prior to a flight to a point outside the 
United States. 

(2) Flights to a base where repairs, 

alterations or maintenance are to be 
performed, or to a point of storage, or 
for the purpose of returning an aircraft 
to service. 

(3) Official visits by representatives 

of foreign governments. 

(4) Other flights the Administrator 

determines, after consultation with the 
Administrator of the EPA, to be for 
short durations at infrequent intervals. 
A request for such a determination 
shall be made before the flight takes 
place. 

(b) 

Exemptions for very low production 

engine models. 

The emissions standards 

of this part do not apply to engines of 
very low production after the date of 
applicability. For the purpose of this 
part, ‘‘very low production’’ is limited 
to a maximum total production for 

United States civil aviation applica-
tions of no more than 200 units covered 
by the same type certificate after Jan-
uary 1, 1984. Engines manufactured 
under this provision must be reported 
to the FAA by serial number on or be-
fore the date of manufacture and ex-
emptions granted under this provision 
are not transferable to any other en-
gine. This exemption is limited to the 
requirements of § 34.21 only. 

(c) 

Exemptions for new engines in other 

categories. 

The emissions standards of 

this part do not apply to engines for 
which the Administrator determines, 
with the concurrence of the Adminis-
trator of the EPA, that application of 
any standard under § 34.21 is not justi-
fied, based upon consideration of— 

(1) Adverse economic impact on the 

manufacturer; 

(2) Adverse economic impact on the 

aircraft and airline industries at large; 

(3) Equity in administering the 

standards among all economically 
competing parties; 

(4) Public health and welfare effects; 

and 

(5) Other factors which the Adminis-

trator, after consultation with the Ad-
ministrator of the EPA, may deem rel-
evant to the case in question. 

(d) 

Applicants seeking exemption from 

other emissions standards of this part and 
40 CFR part 87. 

Applicants must request 

exemption from both the FAA and the 
EPA, even where the underlying regu-
latory requirements are the same. The 
FAA and EPA will jointly consider 
such exemption requests, and will as-
sure consistency in the respective 
agency determinations. 

(e) Applications for exemption from 

this part shall be submitted in dupli-
cate to the Administrator in accord-
ance with the procedures established 
by the Administrator in part 11. 

(f) The Administrator shall publish in 

the F

EDERAL

R

the name of the 

organization to whom exemptions are 
granted and the period of such exemp-
tions. 

(g) No state or political subdivision 

thereof may attempt to enforce a 
standard respecting emissions from an
