Data Pertinent to All Models: 
 
Serial Numbers Eligible: The following serial numbers are eligible for a U.S. Standard Airworthiness Certificate if all import  
(See NOTE 7) requirements of this TCDS are satisfied:  
 MDM-1 “Fox”:  Serial numbers 248 and subsequent 
 MDM-1P “Fox-P”:  Serial numbers 248 and subsequent 
 
The following serial numbers were produced prior to issuance of the U.S. Type Certificate and will 
therefore not have a Polish Civil Aviation Authority (CAA), Export Certificate of Airworthiness 
(Export C of A) that contains the reference to the FAA Type Certificate G00069CE.  They are 
eligible for a U.S. Standard Airworthiness Certificate if the TC Holder Service Bulletin No. BO-
22/2015 MDM-1 FOX, original issue dated April 29, 2016, or later approved revision, is 
incorporated, and the other applicable requirements of this TCDS are satisfied, except as specified 
in the noted Service Bulletin:  
 MDM-1 “Fox”:  Serial numbers P14, P-16, and 201-247 
 MDM-1P “Fox-P”:  Serial numbers P-14, P-16, and 201-247 
 
Import Requirements: The FAA can issue a U.S. airworthiness certificate based on the Polish CAA Export C of A signed  
(See NOTE 7) by a representative of the CAA on behalf of the European Community. The Export C of A should 
contain the following statement: “The aircraft covered by this certificate has been examined, tested, 
and found to conform to the type design approved under FAA Type Certificate G00069CE and to 
be in a condition for safe operation.”   
 
Refer to the applicable bilateral agreement to verify eligibility for import into the Uni ted 
States of both new and used aircraft based on the scope of the agreement, to identify any 
required statements by the exporting authority on the Export C of A (or equivalent 
document), and for procedures for coordinating exceptions to conformity stateme nts on 
these documents. Refer to FAA Order 8130.2, Airworthiness Certification of Aircraft, for 
requirements for issuance of an airworthiness certificate for imported aircraft. 
 
Certification Basis: 1) Title 14 of the Code of Federal Regulations (14CFR) Part 21, effective February 1, 1965, 
including Amendments 21-1 through 21-60 as applicable.  
 
2) Joint Airworthiness Requirements for Sailplanes and Powered Sailplanes (JAR-22), Change 4, 
dated May 7, 1987. 
 
3) Exemption (JAR 22.49) – Stall speed with two person crew exceeds 80 km/hr (Aerobatic 
version only).  
 
4) Exemption (JAR 22.143) – Airbrakes closing force exceeds 20 daN. 
 
5) Date of application for FAA Type Certificate: September 5, 2014. 
 
6) Type Certificate No. G00069CE issued May 13, 2016. 
 
7) The following kinds of operation are allowed: 
- VFR-Day  
- IFR – Day (If properly equipped.  See “Cloud Flying” in NOTE 6) 
 
The Polish Civil Aviation Authority (CAA) originally type certificated the MDM-1 “Fox” glider 
under its Type Certificate No.BG-197 issued on July 27, 1994.  The MDM-1P “Fox-P” glider was 
subsequently certified and added to Type Certificate No. BG-197 on January 12, 1999.  Effective 
May 01, 2004, the European Aviation Safety Agency (EASA) began oversight of these products on 
behalf of the CAA.  The EASA TCDS number is EASA.A.039.

5 G00069CE 
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 Flight Manual 
for Models MDM-1 “Fox” and MDM-1P “Fox-P”, Issue V, Revision 0, dated April 29, 2016, or 
later approved revision, is required. 
 
1) Minimum equipment: 
- Airspeed indicator 
- Altimeter 
- Accelerometer (when used for aerobatic flight) 
- 5-points pilot harness 
- Parachute or back cushion for each crew member (where cushion thickness is 
approximately 3 in (8 cm) on front seat and 1 in (2 cm) on rear seat) 
 
Refer to the Flight Manual for additional equipment. 
 
Service Information: Each of the documents listed below must state that it is approved by the European Aviation Safety 
Agency (EASA) or – for approvals made before May 01, 2004 – by the Polish Civil Aviation 
Authority (CAA). 
- Flight Manual 
- Technical Service Manual 
- Service Bulletins 
- Vendor manuals 
 
The FAA accepts such documents and considers them FAA-approved for type design data only 
unless one of the following conditions exists: 
- The documents change the limitations, performance, or procedures of the FAA approved 
manuals.  
 
The FAA uses the post type validation procedures to approve these documents.  The FAA may 
delegate on a case-by-case basis to EASA to approve on behalf of the FAA for the U.S. type 
certificate.  If this is the case it will be noted on the document.  
 
Available service documents: 
 
1) Flight Manual for Models MDM-1 “Fox” and MDM-1P “Fox-P”, Issue V, Revision 0, dated 
April 29, 2016, or later approved revisions 
 
2) Technical Service Manual for Models MDM-1 “Fox” and MDM-1P “Fox-P”, Issue IV, 
Revision 0, dated April 29, 2016, or later approved revisions 
 
3) Operating Instructions: Tost model “E 85” nose tow release, latest approved version 
 
4) Operating Instructions: Tost model “Europa G 88” safety tow release, latest approved version 
(if installed) 
 
NOTES: 
 
NOTE 1. Current weight and balance data together with list of equipment included in certificated empty weight, and 
loading instructions, when necessary, must be provided for each glider at the time of original certification. 
 
NOTE 2. The placards listed in Flight Manual must be displayed.  Flight Manual Limitations may not be changed 
without FAA approval. 
 
NOTE 3. Section 4, "Airworthiness Limitations" of the Technical Service Manual for Models MDM-1 “Fox” and 
MDM-1P “Fox-P” are FAA-approved.  These Airworthiness Limitations may not be changed without FAA 
approval. 
 
NOTE 4. All external portions of the glider exposed to sunlight must be painted white except the areas for registration 
numbers, wing tips outboard of the ailerons, fuselage nose, and rudder. 
 
NOTE 5. Information essential for the proper operation, maintenance and repair of the glider is contained in the Flight 
Manual and Technical Service Manual for Models MDM-1 “Fox” and MDM-1P “Fox-P”. 
 
NOTE 6. “Cloud Flying” is considered flying in Instrument Meteorological Conditions (IMC) and requires an 
Instrument Flight Rules (IFR) clearance in the U.S.  This is permissible in the U.S. provided the pilot has the

6 G00069CE 
 
appropriate rating per 14 CFR 61.3, the glider contains the necessary equipment specified under 14 CFR 
91.205, and the pilot complies with IFR requirements. 
 
NOTE 7. Gliders produced prior to issuance of the U.S. Type Certificate may have an Export C of A that contains a 
reference to the Polish CAA Type Certificate BG-197 or the EASA Type Certificate EASA.A.039.
