Given that they are constantly being tinkered around these things are expected.I don’t see anything wrong here except for some rough edges/inconsistent panel gaps and below par fit and finish in some areas.
I believe it’s because HAL don’t use automated robots from ABB, KUKA, FANUC etc, that cut the panels with laser precision.
Not to mention a Composit is much more tough to cut precisely than an aluminium or steel sheet Chinese use in JF17/FC1.
I believe Tata aerospace has access to more advanced manufacturing/assembly tools than a Govt PSU ie HAL.
PS: This particular LCA was from IOC batch which can be confirmed by other photos taken by the same Pakee photographer who to me was more interested in finding flaws in this Indian bird and therefore avoided to take close up snaps fof FOC versions standing nearby . So it’s not that surprising that it has inconsistent panel gaps, rough edges and poor paint quality.
how can we expect the assemblers to know such thing?
