In the matter of the petition of 

 Exemption No. 17324

Wittman Regional Airport Regulatory Docket No. FAA-2016-4042

Oshkosh, Wisconsin 

for an exemption from § 139.101 

of Title 14, Code of 

Federal Regulations 

 

FULL GRANT OF EXEMPTION

By letter dated February 8, 2017, Mr. Peter M. Moll, Airport Director, Wittman Regional 

Airport (KOSH), 525 W. 20th Avenue, Oshkosh, Wisconsin 54902-6871 petitioned the 

Federal Aviation Administration (FAA) on behalf of the airport for an exemption from 

§ 139.101 of Title 14, Code of Federal Regulations (14 CFR). The proposed exemption, if 

granted, would allow the airport to permit specific unscheduled air carrier operations at 

Wittman Regional Airport (KOSH) at limited times during the Experimental Aircraft 

Association (EAA) AirVenture Oshkosh, July 24-30, 2017 event.

The petitioner requests relief from the following regulation:

Section § 139.101 prescribes, in pertinent part, no person may operate an airport specified 

under § 139.1 of this part without an Airport Operating Certificate or in violation of that 

certificate, the applicable provisions, or the approved Airport Certification Manual. 

The petitioner supports its request with the following information:

The petitioner states KOSH is a large, general aviation airport comprised of approximately 

1,400 acres. One hundred and sixty-three aircraft are based at the airport, ranging from turbine 

corporate aircraft and large piston multi-engine aircraft to gyrocopters. The airport sees nearly 
70,000 aircraft operations annually, of which approximately 18,000 occur during the 10-day 

period around the EAA AirVenture Oshkosh. 

The petitioner states that EAA AirVenture Oshkosh is the largest fly-in event in the world. 

More than 10,000 aircraft visit KOSH over the course of one week. General aviation aircraft 

make up the vast majority of those visiting aircraft. Despite this, the airport receives requests 

to operate unscheduled charter operations or air carrier operations.

Limited unscheduled charter operations occur during EAA AirVenture, bringing attendees to 

the event. The aircraft are operated by 14 CFR Part 121-certified air carriers. As a general 

aviation airport, both of these operations would necessarily call for the airport to meet the 

requirements of 14 CFR Part 139.101. These charter and air carrier operations are essential to 

the continued success of EAA AirVenture, necessitating an exemption from 14 CFR Part 

139.101 during the July, 2017 event.

The petitioner advises due to the scheduling nature of these operations, the specific 

aircraft type to be utilized cannot be reasonably determined within the time constraints 

required to file this petition. The following table lists the aircraft type and schedule

operated during AirVenture 2017.

KOSH is seeking relief from 14 CFR Part 139.101 for similar operations during EAA 

AirVenture 2016. The operations during the 2017 event may include, but are not limited 

to, the above aircraft. Operations of aircraft to KOSH will be limited to aircraft no larger 

than ARFF Index C-category aircraft, with seating capacities of no greater than 240 

passengers.

The petitioner proposes the following safety mitigations and standards as an alternative to 

holding an airport operating certificate for the duration of the July, 2017 EAA AirVenture 

event:
Airport Certification Manual

KOSH will maintain and comply during air carrier operations with a current Airport 

Certification Manual (ACM) throughout the exemption period. All airport tenants and 

stakeholders in the ACM will have the opportunity to share, review and discuss their 

applicable portions of the manual. These participants include, but are not limited to 

management and personnel from airport management and maintenance/operations, 

Oshkosh Fire Department (ARFF), Winnebago County Sheriff's Department, 

Winnebago County Emergency Management, Oshkosh Police Department, Federal 

Aviation Administration Air Traffic Control (FAA ATCT), FAA Technical Operations, 

EAA, Basler Flight Service, and Myers Aviation.

Operations

KOSH is responsible for, will train, and maintain records of all personnel who have 

driving privileges on the airport, particularly those who have access to runway safety 

areas. Topics in this training include airport familiarization, signage, pavement markings, 

radio communications, and access to safety areas. This includes, but is not limited to,

airport maintenance/operations staff, FAA Technical Operations staff, tenants who may 

assist in aircraft maintenance/recovery, ARFF and security personnel, and EAA 

employees/volunteers who have a need to access operational surfaces.

All safety areas will be maintained and controlled in accordance with 14 CFR Part 139.309.

Signage, pavement markings, and lighting necessary for aircraft operations will be 

maintained per 14 CFR Part 139.311 and will further be in accordance with the 

Signage Plan submitted with the Airport Certification Manual.

Airport Rescue and Fire Fighting (ARFF) Requirements

To mitigate safety risks to aircraft occupants as well as persons and property on the 

ground, and to further comply with applicable sections of 14 CFR Part 139, the following 

actions will be taken during applicable air carrier operations:

 ARFF equipment is provided with a minimum capacity of 3,000 gallons of water 

for AFFF production along with firefighters who have received live fire training 

and additional training as outlined in 14 CFR Part 139.319(i) in the past 12 

months. Additional firefighting apparatus from the City of Oshkosh Fire 

Department are on standby status at the airport fire station or can respond to any 

incidents on the airport.

 ARFF equipment will be located at pre-determined positions on the airport a 

minimum of 15 minutes before the arrival and departure of these aircraft and 

will remain a minimum of 15 minutes after the operation is complete.

 ARFF vehicles fire suppression systems are tested annually prior to EAA 

AirVenture Oshkosh by the vehicle manufacture; this includes dry chemical and 

refractometer testing of each applicable system.

specific training curriculum. The City of Oshkosh Fire Department is 

responsible for maintaining the ARFF training curriculum and records of all 

training given to each individual.

 Live Fire Training

 All ARFF personnel that will be on duty on the day of the planned charter 

flight(s) shall participate in a live-fire drill prior to initial performance of 

ARFF duties and participate in live-fire training at least once every 12 

months at an FAA acceptable Regional ARFF training facility.
 Basic Emergency Medical Training

 The City of Oshkosh Fire Department is responsible for providing training 

for, and maintaining the records of all firefighter and Emergency Medical 

Services (EMS) personnel. These personnel will be providing medical 

services during EAA AirVenture.

Emergency Plan 

The Emergency Plan outlined in Part 139.325 is reviewed by all plan stakeholders prior 

to the commencement of EAA AirVenture Oshkosh. This review is conducted in 

conjunction with a tabletop exercise of the EAA AirVenture Oshkosh emergency plan. 

The stakeholders of each plan comprise the same individuals and agencies.

Fueling Operations 

 Fueling of all 14 CFR Part 139-related flights will be conducted by Basler Flight 

Service.

 The fuel supervisor receives biennial training through the National Air 

Transportation Association (NATA) Safety 1st Supervisor Online Training course 

for 14 CFR 139.321(b)(1) through (b)(6) and 139.321(e)(1). This individual 

further trains all other line personnel in refueling operations for 14 CFR Part 139 

operations.

 Each employee additionally receives live fire extinguisher training 

annually prior to the commencement of EAA AirVenture Oshkosh.

 Each fueling employee will also receive driver training from airport management 

on airport familiarization, signage, pavement markings, and communications, 

even though these personnel are restricted from operating fueling vehicles on air 

operations areas.

Airfield Operations Safety

 KOSH management and maintenance/operations personnel are all trained in airport 

self-inspection procedures and conduct inspections at least twice daily prior to 

FAA ATCT opening and after FAA ATCT closing. Additional inspections are 

conducted as needed during the day, as requested by ATCT or upon reports by 

pilots or personnel of runway contaminants.

 Arrivals and departures of air carrier aircraft will operate from Runway 18R-36L 

exclusively.

 Arrivals and departures of air carrier aircraft will only be conducted during times 

when the airport and ATCT are operational (0600 local to 2000 local).

 The Runway 18R-36L safety areas of 500 feet wide and 1000 feet long off the 

arrival/departure ends of the runway will be clear of aircraft, personnel, vehicles, 

and any object not fixed by function during air carrier operations.
 Runway 18R-36L shall be inspected by trained Wittman Regional Airport 

maintenance and management personnel prior to each air carrier operation. Up to 

ten (10) airport personnel are on duty at any time during air carrier operations. 

Each employee has received training in all aspects of 14 CFR 139.303.

 KOSH enters into a Letter of Agreement (LOA) with the FAA- ATCT, Oshkosh 

Fire Department, and Experimental Aircraft Association annually to outline 

procedures for aircraft emergency responses during EAA AirVenture Oshkosh.

 KOSH enters into a Letter of Agreement (LOA) with FAA-ATCT and 

Experimental Aircraft Association for control of aircraft movement and nonmovement areas on the airport during EAA AirVenture Oshkosh.

The FAA has determined that good cause exists for not publishing a summary of the 

petition in the Federal Register because the requested exemption would not set a precedent, 

and any delay in acting on this petition would be detrimental to the Wittman Regional 

Airport.

The FAA analysis is as follows:

The EAA AirVenture event has been operating from KOSH since 1969. Over the years, the 

event and number of participants has grown exponentially, with the FAA contributing its

support and safety oversight of this event each year. The FAA Regional Airport Office in the 

Great Lakes Region (AGL) is the assigned Office of Airports safety oversight. This oversight 

includes the assignment of an airport certification safety inspector to conduct a Part 139 

airport inspection annually in preparation for this event. For the purposes of hosting the EAA 

AirVenture each year, KOSH has agreed to adhere to the Part 139 standards and requirements 

outlined in 14 CFR Part 139.101. 

Further historical data revealed KOSH was first issued an Airport Operating Certificate 

(AOC) in May 1973 to support scheduled air carrier service. For the past 43 years, KOSH has 

been annually and periodically inspected for compliance with Part 139 requirements, whether 

or not it held at that time an airport certificate. In August 2010, scheduled air carrier service 

was suspended and per regulation, KOSH elected to surrender its AOC to the FAA Great 

Lakes Regional Airport office. However, it is important to note: due to the airports’ familiarity 

with Part 139 requirements to obtain and maintain an AOC, and the continuation of the EAA 

AirVenture event, the airport has been subjected to the annual Part 139 inspection, despite not 

holding an AOC. From 2010-2015, KOSH was issued a Time-Limited AOC, in order to host 

the EAA AirVenture event. However, Time-Limited AOCs are not consistent with Part 139. 

As in 2016, the airport petitioned for an exemption from 14 CFR Part 139.101 to permit it to 

host the EAA AirVenture 2017. The FAA issued Exemption No. 17035 (copy enclosed) in 

circumstances substantially similar to those presented in this petition.

The safety mitigations stated above are consistent with Part 139 regulation and requirements.

The FAA Airport Certification Safety Staff located in the Great Lakes Region through annual 

Part 139 airport certification safety inspections has verified the airport is properly and 

adequately equipped to conduct the proposed air carrier operations. Furthermore, the annual 

airport inspections have validated the relevant airport characteristics, facilities, and 
equipment, including: landing area dimensions, strength, and condition; applicable clearances; 

airport marking, signage, and lighting; firefighting and rescue capability; wind direction 

indicators; and airport safety surveillance capability.

These circumstances and mitigations ensure that granting this exemption would not adversely 

affect safety. Additionally, as described in Exemption No. 17035, the FAA finds that a grant 

of exemption is in the public interest.

The FAA decision is as follows:

In consideration of the foregoing, I find that a grant of exemption is in the public interest. 

Therefore, pursuant to the authority contained in 49 U.S.C. §§ 106(f), 40113, and 44701, 

delegated to me by the Administrator, Wittman Regional Airport (KOSH) is granted an 

exemption from 14 CFR § 139.101 to the extent necessary to allow limited air carrier 

operations, not to exceed six flight operations for EAA AirVenture 2017, subject to the 

conditions and limitations listed below.

Conditions and Limitations
