E-PROPS : quality, EASA certification, ASTM F2506-13, Service Bulletins, Service Letters
The E-Props propellers are designed, manufactured and tested to meet the requirements of the aeronautical standards.
Quality and safety are ongoing concerns for the E-PROPS company, throughout the design, procurement, manufacturing, testing and marketing of all its products.
1- EASA / DGAC CERTIFICATION
2- ASTM F2506-13 (LSA)
3- SERVICE BULLETINS
4- SERVICE LETTERS
At the end of 2021, E-PROPS has initiated the following procedures:
- with French DGAC, application for a Production Organization Approval (POA) according to EASA Part 21 subpart G
- with EASA, application for Type Certificates for some E-Props models suitable for use on certified aircraft
Work is in progress with the certification agencies.
The E-PROPS propellers (DURANDAL & EXCALIBUR ranges) meet the ASTM F2506-13 standards, for the Light Sport Aircraft (LSA).
The ASTM F2506-13 specification covers the establishment of the minimum requirements for the design, testing, and quality assurance of fixed-pitch or ground adjustable propellers for Light Sport Aircraft. Strength testing, stress measurement, fatigue strength, and fatigue analysis, endurance testing, and teardown inspection shall be performed to meet the requirements prescribed.
The Service Bulletins are published by the manufacturers of aeronautical products. They are established to prevent the users of a technical problem, a novelty or an improvement of an aeronautical product, as well as to transmit a technical information concerning the use of an aeronautical product.
The Service Bulletins issued by the E-PROPS company are available hereafter.

BULLETIN SERVICE BS REF HEP-BS-20-002F
PLEASE NOTE => this recommendation only applies to E-PROPS EXCALIBUR-6 model with Rotax serie 9 on gyrocopters.
Date : 21 janvier 2020
Hélices concernées : E-PROPS à pas réglable au sol modèle EXCALIBUR-6 pour autogires montées sur moteurs Rotax série 9 (avec réducteur).
Suite au Bulletin d'Information ref BI 2020-ULM-01 publié par la DGAC le 10-01-2020 et au Bulletin Service E-PROPS ref HEP-BS-20-001F publié le 11-01-2020, plusieurs propriétaires d'autogires équipés d'hélices EXCALIBUR-6 se sont mis en contact avec la société E-PROPS. Ils ont envoyé des éléments techniques sur leurs montages, ainsi que des photos.
Les investigations menées par le Bureau d'Etudes E-PROPS ont fait apparaître plusieurs non-conformités IMPORTANTES et DANGEREUSES dans des montages d'hélices E-PROPS 6-pales propulsives modèle EXCALIBUR-6 sur autogires.
Actions correctives :
E-PROPS recommande à tous les utilisateurs d'hélices E-PROPS 6-pales propulsives EXCALIBUR-6 montées sur autogires de vérifier très soigneusement le système de fixation de leur hélice à l'aide des informations communiquées dans le présent document et dans le Manuel de Montage et d'Entretien des hélices E-PROPS.
Si les vis, les espaceurs, le montage ou le serrage ne semblent pas conformes, ne volez pas avec votre autogire et contactez immédiatement E-PROPS.

BULLETIN d'INFORMATION DGAC REF BI 2020-ULM-01 Révision 1
PLEASE NOTE => this recommendation only applies to E-PROPS EXCALIBUR-6 model with Rotax serie 9 on gyrocopters.
The propellers were expertised by the DGA and the E-PROPS EXCALIBUR-6 propellers were cleared.
This document, written and signed by the French Aviation Department states:
- no [Excalibur-6] propeller manufacturing defects or structural weaknesses were found
- the most likely cause of the partial disassociations is a failure to follow the assembly, tightening and inspection instructions published by E-Props
