What time did she arrive at Narita Airport?
Literal
She [topic-は] Narita-Airport [at-に] what-time [at-に] arrived [explanatory-のですか]?
成田空港 (なりたくうこう) is Narita International Airport, Japan's primary international gateway serving the greater Tokyo area. 何時に (なんじに) asks 'at what time.' The のですか ending adds an explanatory/seeking-context nuance — the questioner wants to understand the circumstances, not just the bare time.
