§ 91.863

Transfers of Stage 2 airplanes 

with base level. 

(a) Stage 2 airplanes may be trans-

ferred with or without the cor-
responding amount of base level. Base 
level may not be transferred without 
the corresponding number of Stage 2 
airplanes. 

(b) No portion of a U.S. operator’s 

base level established under § 91.861(a) 
may be used for operations by a foreign 
air carrier. No portion of a foreign air 
carrier’s base level established under 
§ 91.861(b) may be used for operations 
by a U.S. operator. 

(c) Whenever a transfer of Stage 2 

airplanes with base level occurs, the 
transferring and acquiring parties 
shall, within 10 days, jointly submit 
written notification of the transfer to 
the FAA, Office of Environment and 
Energy. Such notification shall state: 

(1) The names of the transferring and 

acquiring parties; 

(2) The name, address, and telephone 

number of the individual responsible 
for submitting the notification on be-
half of the transferring and acquiring 
parties; 

(3) The total number of Stage 2 air-

planes transferred, listed by airplane 
type, model, series, and serial number; 

(4) The corresponding amount of base 

level transferred and whether it is U.S. 
operator or foreign air carrier base 
level; and 

(5) The effective date of the trans-

action. 

(d) If, taken as a whole, a transaction 

or series of transactions made pursuant 
to this section does not produce an in-
crease or decrease in the number of 
Stage 2 airplanes for either the acquir-
ing or transferring operator, such 
transaction or series of transactions 
may not be used to establish compli-
ance with the requirements of § 91.865.
