The test crew who were assessing the quality of the turboprop aircraft before purchase were killed in the crash.
The Royal Malaysian Air Force also has an A400M, delivered in March.
The plane was assembled in Spain as part of a joint NATO programme.
The black boxes attest to that, Lahoud told Handelsblatt.
There are no structural defects, but we have a serious quality problem in the final assembly.
The military was using the Spanish aircraft there to perform pre-acceptance testing on the aircraft.
Out of 174 A400M planes, only 12 so far have been put into active service.
It is a precautionary measure which is part of our continued airworthiness activities, a spokeswoman told Reuters.
