1. Comments to LISI
   EN3740 ; ASD-Cert 392-1-7

   1. EN 9100 is expired since 06.2019.

   Qualification performed in November 2017 (QTP and QTR issued in September 2018 )
   Are there any explanation between “Tests performed in November 2017 and report issued in September 2018.

   2. QTR 010-18 EN 3740-080; page 10; Tensile Test Results
   The requirements for the 080 size in line with ISO is 46KN. The report showed 20kN. There is an inconsistency to the Double shear test results which correspond to the-080 size (66KN)

   3. Tension Fatigue Test results para 5.4.3 (for all sizes)
   There are no load values listed in the report. Only number of cycles are listed without any load values.
   Test were performed in May 2016. Can this be accepted regarding the time between tests and report?

   4. QTR 010-18 EN 3740-100; page 12; Tensile Test Results
   The requirements for the 080 size in line with ISO is 72KN. The report showed 46kN. There is an inconsistency to the Double shear test results which correspond to the-100 size (104KN)

   5. Fatigue Test Result for -100, page 13
   Explanation why no tested up to 130 000 cycles for all test samples. Are there failure occurred, or did the test facility stopped?

   6. QTR 010-18; EN 3740-150 Tensile Test Results page 14
   What is the reason to use MPa instead on KN. The Technical Specification requires a load. Reason to provide values in MPa? Are these calculated values?
   Explanation is necessary where are the values from. We know that this is a drilled shaft.

   8. Question / Clarification to Annex 4, 5,6,7

   Size Material
   Lot MO Date Valid COC
   Annex 4 NDT Check
   Annex 5 Heat Treatment
   Annex 6 Plating /Coating
   Annex 7
   050 760090 24.05.2016 09.05.2016 28.04.2016 21.05.2016 until 23.5.2016
   060 764318 20.12.2016 19.12.2016 07.12.2016 19.12.2016
   080 760011 25.05.2016 05.05.2016 27.04.2016 21.05.2016
   100 760007 27.05.2016 07.05.2016 28.04.2016 23.05.2016
   150 760009 01.06.2016 11.05.2016 28.04.2016 23.05.2016
   170 760010 06.06.2016 18.05.2016 No data 24.5.2016 until 25.5.2016

   Can you explain why the “Material MO Date Valid COC in Annex 4” have a later date than all the other dates of the different processes?
