SpiceJet (SG, Delhi International) has said in a notice to the stock market that it will resume operations of all three B737-700(F)s on the basis of a "resolution provided by Israel Aerospace Industries".

The Indian carrier previously grounded all three units converted by IAI after the manufacturer discovered "an apparent irregularity" possibly leading to unsafe situations during emergency landings. The three narrowbody freighters had been inactive since December 11.

Although SpiceJet said that it will resume operations of all three B737-700(F)s on December 23, Flightradar24 ADS-B data indicates that only one unit, VT-SFE (msn 29084), was reactivated on December 19 already. The other two aircraft remain grounded.

SpiceJet also operates a single B737-800(F) which was not converted by IAI and was not affected by the grounding.

The discovered "irregularity" relates to the so-called rigid barrier separating the cockpit and the freight deck. On December 12, 2019, the Civil Aviation Authority of Israel (CAAI) issued an emergency airworthiness directive related to all B737-300s, -400, and -700 passenger-to-freighter jets converted by IAI, requiring operators to "reduce the cargo weights per each loading configuration and use of additional straps when necessary".
