Title 740 CMR 24.00 - Logan Airport Noise Abatement
Section 24.05 - Noise Abatement Ground Procedures

Universal Citation: 740 MA Code of Regs 740.24

Current through Register 1531, September 27, 2024

(1) Between the hours of midnight and 6:00 a.m., the Executive Director may prohibit operation of any aircraft engine or aircraft electrical power generating device (except in conjunction with a flight arrival or flight departure) which generates a noise level in excess of 5dB above ambient at any noise monitoring system microphone located in or adjacent to a residential community. Failure to comply with the instruction given by the Executive Director is a violation of 740 CMR 24.05.

(2) Aircraft engine run-ups, except for reciprocating engine run-ups performed as part of pre-takeoff procedures, are prohibited between midnight and 7:00 a.m.

(3) Aircraft engine run-ups (except for reciprocating engine run-ups performed as part of pre-takeoff procedures) shall not be performed between 7:00 a.m. and midnight, unless prior approval of the Executive Director has been obtained. The Executive Director shall not withhold approval for performance of such operations at specific times and places as he shall designate and of which he shall provide notice to aircraft operators prior to the effective date of 740 CMR 24.00.

(4) Idle power aircraft engine run-ups between the hours of midnight and 6:00 a.m. shall not be performed unless prior approval of the Executive Director has been obtained. The Executive Director shall not withhold approval for performances of such operations at specific times and places as he shall designate and of which he shall provide notice to aircraft operators prior to the effective date of 740 CMR 24.00.

(5) Aircraft taxiing to Runway 22R shall hold short of the designated noise abatement hold line on November taxiway, until cleared to proceed by Boston Tower. The hold line is identified by pavement marking and a sign reading "Hold Point-Runway 22R".

(6) Aircraft taxiing to Runway 27 shall hold short of the designated noise abatement hold line on Delta taxiway, until cleared to proceed by Boston Tower. The hold line is identified by pavement marking and a sign reading "Hold Point - Runway 27".

(7) The following noise abatement rules govern within the North Hangar Area:

(a) Jet engine starts and the taxiing of jet aircraft on the extension of Outer Taxiway or the Hangar Apron northwesterly of the fuel farms, is prohibited.

(b) Jet aircraft departing the airfreight terminal ramps in the northwesterly corner of the North Hangar Area shall be pushed out to a position permitting straight out taxi, aligned with the North Apron Taxiway centerline.

(c) Should the operation of APUs or GPUs be necessary between the hours of 11:00P.M. and 7:00 A.M., the aircraft shall be positioned so that the APU exhaust or GPU equipment is shielded from the nearest residential area by the fuselage of the aircraft.

(8) The following noise abatement rules govern within the South Hangar Area.

(a) No jet or turboprop aircraft or helicopters shall be operated westerly of the east general aviation terminal ramp under their own power. The movement of such aircraft or helicopters beyond that point will be permitted only if under tow both in and out.

(b) All jet and turboprop aircraft parked at the east general aviation terminal ramp shall be positioned on a heading of 310 degrees magnetic.

(c) Should the operation of APUs or GPUs be necessary between the hours of 11:00P.M. and 7:00 A.M., the aircraft shall be positioned so that the APU exhaust or GPU equipment is shielded from nearest residential areas by the fuselage of the aircraft.

(d) No stationary aircraft in the South Hangar Area or on the South Taxiway, except an aircraft at an air passenger gate or at a maintenance hangar shall operate a jet engine or an APU for more than 15 minutes in a single interval without prior approval of the Executive Director.

(9) Between the hours of 11:00 P.M. and 7:00 A.M. slight training operations including but not limited to practice approaches and takeoffs or landings shall not be conducted at the airport, exclusive of the initial take off and final landing of a training flight conducting such training activities elsewhere, for which take off or landing a temporary waiver has been granted by the Executive Director.

(NOTE: 740 CMR 24.05(10) was formerly Part E, Article IV, section J of the Rules and Regulations for Logan International Airport.)

(10)

(a) Takeoffs from Runway 4L shall be limited to aircraft with a takeoff noise emission level of 73 dBA or less and landings on Runway 22R shall be limited to aircraft with a landing specified noise emission level 78 dBA or less. For purposes of 740 CMR 24.05 the term "specified noise level" shall mean the noise level for the type of operation in question (i.e., landing or takeoff) as published in the FAA Advisory Circular.

(b) Takeoffs on 4L and landings on 22R are prohibited between the hours of 11:00 P.M. to 6:00 A.M.

(c) An exemption from the prohibitions set forth in 740 CMR 24.05(10)(a) and/or (b) may be granted by the Executive Director under unusual operating circumstances such as when alternative runways are closed or otherwise unavailable or as required to accommodate emergencies.

(11) Intersection takeoffs by jet aircraft or aircraft exceeding 30,000 pounds maximum certificated gross takeoff weight are prohibited, except for departures from Runway 15R

(12) No aircraft on landing shall intentionally be touched down short of any designated displaced threshold, except that this requirement shall not apply to Runway 4R under day VFR conditions.

(13) Should a turboprop or jet aircraft utilize a runway for landing or takeoff other than the preferential noise abatement runway initially assigned by Boston Tower according to the preferential runway procedures set forth in any current FAA Boston Tower Standard Operating Procedure a report of the reasons for such use shall be filed by the operator of such aircraft upon the request of the Executive Director.

(14)

(a) Notwithstanding any provision of these regulations to the contrary, the Executive

Director is hereby authorized to allow part-power aircraft engine run-ups during the period 6:30 A.M. to 7:00 A.M. as part of a routine aircraft maintenance check at designated areas of the airport. The authorization granted hereunder shall not exceed a one year period in order to allow the Executive Director the opportunity to monitor and analyze the effects of such a rule in terms of:

1. environmental impact;

2. improvements to airport and air carrier operating efficiency;

(b) The Executive Director shall report to the Board following the conclusion of the review period with a specific recommendation as to whether or not a further amendment to 740 CMR 24.00 is advisable.

(c) Any air carrier may petition the Executive Director for authorization to conduct such part-power run-up by specifying the particular operation(s) for which such exemption is sought. Such petition will be granted upon the agreement of the air carrier to comply with reasonable controls in order to permit appropriate monitoring and limit environmental impacts, provided, however, that the Executive Director may:
(i) limit the areas of the airport within which such run-ups can be conducted in order to avoid excessive environmental impacts; and/or

(ii) terminate the experiment if the monitoring results indicate that the environmental harm outweighs the potential or actual operating benefits.
