Narrative:

It has come to my attention that I have misinterpreted a maintenance step; as well as inspected incorrectly due to my misinterpretation. While performing maintenance on three erj-170 aircraft; performing company engineering order (eo) XXXX-001; to comply with airworthiness directive (ad) 2013-03-13; to install an improved hinge and striker on the flight deck door; a roll pin may have not been installed correctly into the lower door hinge embraer aircraft illustrated parts catalog (aipc) (52-51-01; figure 05; item 190). I performed and inspected the step incorrectly; possibly resulting in the cockpit door not being secure; and the ad to not have been complied with properly. Eo XXXX-001 instructs me to verify the [roll] pin is installed correctly and refers to the pin as (elastic pin); and also that the pin is not included in the parts kit issued to the task. I verified the step in the aircraft maintenance manual (amm) (52-51-01-820-801-a; ((east) (1); (b) (1); (b)) and checked the part number (P/north) in the aipc (52-51-01; figure 05; item 190; P/north PE25041-055-03). The aforementioned P/north is indeed included in the parts kit issued to the task; (quantity two). I believed it was a mistake on the eo stating it was not included since it is the same P/north. I believe contributing factors are the possibility that the nomenclature of the part has been lost in translation from brazilian portuguese to american english. The common name for the part is a (roll pin); referred to in the amm as an (elastic pin); and printed on the parts bag is (pino elastico). [Recommend to] inspect cockpit door hinges on affected aircraft; adjust and install roll pin immediately. Hangar; graveyard [shift].

Title: After accomplishing a company Engineering Order (E/O) for the installation of an improved lower hinge assembly on the flight deck door of multiple ERJ-170 aircraft; an Aircraft Maintenance Technician (AMT) realizes he had misinterpreted one of the maintenance steps and failed to install a required roll pin.

While performing maintenance on three ERJ-170 aircraft; performing company Engineering Order (EO) XXXX-001; to comply with Airworthiness Directive (AD) 2013-03-13; to install an improved hinge and striker on the Flight Deck Door; a roll pin may have not been installed correctly into the lower door hinge Embraer Aircraft Illustrated Parts Catalog (AIPC) (52-51-01; Figure 05; Item 190).
