<h1>Civil Aviation Ministry to issue show cause notice to Air India over wheelchair incident and clogged toilets investigation.</h1> The Civil Aviation Ministry plans to issue a show cause notice to Air India following a complaint regarding the non-availability of a pre-booked wheelchair for an 82-year-old passenger at Delhi airport. The incident, which resulted in the passenger's fall, is under investigation by the DGCA, with CCTV footage being reviewed. Air India claims assistance was provided, but the family disputes this. Additionally, the ministry is investigating a separate incident involving clogged toilets on a Chicago-Delhi flight, which forced the aircraft to return after several lavatories became unserviceable due to items being flushed down.
