Data Pertinent to all Models
Datum Fuselage Sta. (00) is center of most forward lateral fuselage tube.
A pin is located on the lower side of landing gear streamline tube
to indicate datum.
Leveling means Upper Longeron at cockpit
Certification basis Aeronautics Bulletin No. 7-A dated October 1, 1934; FAR 23 dated
February 1, 1967, Amendments 23-1 through 23-7 for powerplant
installation; Type Certificate A18EA issued January 14, 1972. Great
Lakes Company obtained Exemption No. 1163 which granted an
exemption from Section 21.17 of the FAR to permit the issuance of
the Type Certificate incorporating the type design portion of ATC-228.
Production basis Production Certificate Number 328CE
Equipment The basic required equipment as prescribed in the applicable airworthiness
regulations (see Certification Basis) must be installed in the aircraft for
certification.
In addition, the following items of equipment are required:
1. FAA approved Airplane Flight Manual as follows:
a. Serial Nos. 0501 and 0502, approval date July 13, 1973, or
later FAA approved revision as required by STC SA941CE.
b. Serial Nos. 0503 through 0699; approval date Nov. 9, 1973,
or later FAA approved revision.
c. Serial Nos. 0701 through 1199; approval date July 25, 1974, or
later FAA approved revision.
d. Serial Nos. 1200 and up; approval date March 20, 2014 or later FAA approved
revision
NOTE 1. Current weight and balance report together with list of equipment included in certificated empty weight must
be provided for each aircraft at time of original certification. The certificated empty weight and corresponding
center of gravity location must include unusable fuel of 0.0 lb. at (+13.0) and system oil of 1.0 lb. at (-4.0) for
airplanes with Lycoming O-320-E2A engines. Certificated empty weight and corresponding center of gravity
location must include unusable fuel of 4.0 lb. at (+5.0) and system oil of 1.0 lb. at ( -4.0) for airplanes with
Lycoming IO-360-B1F6 and AEIO-360-B1G6 engines.
NOTE 2. All placards specified in FAA Approved Airplane Flight Manual must be displayed in the airplane.
NOTE 3. Reserved.
NOTE 4. Reference CAR 04.61 Dated May 31, 1938, to determine propeller diameter and static r.p.m. limits.
NOTE 5. Serial Nos. 0501 and 0502 are modified by installation of the Lycoming O-320-E2A engine per STC SA941CE;
and Cleveland 20 -80 wheels and brakes, Cleveland IO -5 master cylinders, and Scott tail wheel per STC
SA942CE. These airplanes eligible for certification as 2T- 1A-1 airplanes when Identification Plate 00120 -1
and FAA Approved Airplane Flight Manual for the 2T -1A-1 dated November 9, 1973 with Rev. "B" dated
April 22, 1975, or later FAA approved revision are installed.
NOTE 6. The certification basis for these airplanes does not contain operating categories, i.e., normal, utility or acrobatic,
as listed in current certification regulations. However, since certain of these models were designed to perform
and have demonstrated the capability to perform the acrobatic maneuvers listed in the approved airplane flight
manual plus those maneuvers not exceeding the load factors listed below, the words "acrobatic category" are
included so that those persons concerned with these airpla nes understand their capacity in terms of current
practices. Maneuvering load factors are as follows:
A18EA
Page 6
A. 2T-1A-1 +5.05 to -2.05
B. 2T-1A-2 +5.40 to -4.00
For the above reasons, the airworthiness certificate for 2T-1A-1 and 2T-1A-2 airplanes are to be issued in the
acrobatic category.
NOTE 7. Installation of MTV-9-B-C/C188-18b propeller limited to Serial Numbers 1200 and up.
