This subpart prescribes
aircraft requirements and performance limitations for all certificate holders.
121.153
Aircraft requirements: General
(a) Except as provided in paragraph (c) of this section, no certificate
holder may operate an aircraft unless that aircraft:
(1) Is registered as a civil aircraft of
(2) Is in an airworthy condition and meets the applicable
airworthiness requirements including those relating to identification and
equipment.
(b) A certificate holder may use an approved weight and balance control
system based on average, assumed, or estimated weight to comply with applicable
airworthiness requirements and operating limitations.
(c) A certificate holder may operate in common carriage, and for the
carriage of mail, a civil aircraft which is leased or chartered to it without
crew and is registered in a country which is a party to the Convention on
International Civil Aviation ” ICAO" if:
(1) The aircraft carries an appropriate airworthiness certificate
issued by the country of registration and meets the registration and
identification requirements of that country;
(2) The aircraft is of a type design which is approved by the ECAA and
complies with all of the requirements that would be applicable to that aircraft
were it registered in Egypt, including the requirements which must be met for
issuance of standard airworthiness certificate (including type design
conformity, condition for safe operation, and the noise, fuel venting, and
engine emission requirements), except that an Egyptian registration certificate
and standard airworthiness certificate will not be issued for the aircraft;
(3) The aircraft is operated by crewmembers employed by the
certificate holder, with ECAA licenses validated by the country of
registration; and
(4) The certificate holder files a copy of the aircraft lease or
charter agreement with the ECAA.
121.155
Use of foreign aircrew
The ECAA may grant a
deviation from the crewmembers requirements of 121.153 (c) (3) if the
certificate holder provides adequate justification for using foreign licensed
crewmembers or crewmembers not employed by the certificate holder.
121.157
Aircraft certification and equipment requirements
(a) No certificate holder may operate an aircraft unless that aircraft
was type certificated as a transport category aircraft under Part 25, or
helicopter type certificated under Parts 27 or 29, or as a commuter category
aircraft under Part 23, or equivalent and meets the performance requirements of
its type certificate data sheet and the aircraft meets the requirements of
121.173 (c).
(b) All aircraft operated by an air taxi certificate holder must meet
the performance requirements of its type certificate data sheet, if available,
and all performance data must be approved by the ECAA.
121.159
Single-engine aircraft prohibited
No air carrier certificate
holder may operate a single engine aircraft. Single engine aircraft operated by
air taxi certificate holders shall only be operated in conditions of weather
and light, and over such routes and diversions therefrom, that permit a safe
forced landing to be executed in the event of engine failure.
121.161 Aircraft limitation: Extended range operations
(a) Unless authorized by the ECAA for extended range, based on the
character of the terrain, the kind of operation, or the performance of the
aircraft to be used, no certificate holder may operate two-engine aircraft over
a route that contains a point farther than 1 hour flying time (in still air at
normal cruising speed with one engine inoperative) from an adequate airport.
(b) No certificate holder may operate a land aircraft in an extended
overwater operation unless it is certificated or approved as adequate for
ditching.
(c) For extended range operations, refer to Part 91 appendix A.
121.163
Aircraft proving tests
(a) No air carrier or air taxi certificate holder
may operate an aircraft before that aircraft has been proven for use in air
carrier or air taxi operations, as appropriate, unless an aircraft of that type
has had, in addition to the aircraft certification tests, at least 100 hours of
proving tests acceptable to the ECAA. If the ECAA determines that
a satisfactory level of proficiency has been demonstrated, it may reduce the
number of hours required. The ECAA has the authority to accept, modify or
reject the operator’s plan for the proving tests. At least 10 hours of proving
tests must be flown at night.
(b) A certificate holder may not operate an aircraft of a type that has
been proven for use in its class of operation if it has not previously proved
that type, or if that aircraft has been materially altered in design, unless:
(1) The aircraft has had at least 50 hours of tests acceptable to the
ECAA, including a representative number of flights into enroute airports; or
(2) The ECAA specifically authorizes deviations when special
circumstances make full compliance with this paragraph unnecessary in a
particular case.
(c) An air taxi operator may, with ECAA approval, operate a helicopter
that has not before been proven for use in air taxi operations if the
helicopter has been used extensively in the services of the armed forces and
meets the requirements of paragraph (b) of this section.
(d) For the purposes of paragraph (b) of this section, a type of
aircraft is considered to be materially altered in design if the alterations
include:
(1) The installation of powerplants other than those of a type similar
to those with which it is certificated; or.
(2) Alterations to the aircraft or its components have been made, that
materially affect flight characteristics.
(e) No
certificate holder may carry passengers in an aircraft during proving tests,
except for those needed to make the test and those designated by ECAA, However,
it may carry mail, express, or other cargo, when approved.
